Adhesive taping

Wet-tissue adhesives have long been attractive materials for realizing complicated biomedical functions. However, the hydration film on wet tissues can generate a boundary, forming hydrogen bonds with the adhesives that weaken adhesive strength. Introducing black phosphorus (BP) is believed to enhance the water absorption capacity of tape-type adhesives and effectively eliminate hydration layers between the tissue and adhesive. This study reports a composite patch integrated with BP nanosheets (CPB) for wet-tissue adhesion...

INTRODUCTION: Tape-strips, a minimally invasive method validated for the evaluation of several skin diseases, may help identify asthma-specific biomarkers in the skin of children with allergic asthma. METHODS: Skin tape-strips were obtained and analyzed with RNA-Seq from children with moderate allergic asthma (MAA) (n = 11, mean age 7.00; SD = 1.67), severe allergic asthma (SAA) (n = 9, mean age 9.11; SD = 2...

This research was conducted to apply polyimide tape, which has the advantages of low price ans strong adhesive strength, to the neural electrode process. In addition, to maximize the low-cost characteristics, a fabrication process based on UV laser patterning rather than a photolithography process was introduced. The fabrication process started by attaching the gold sheet on the conductive double-sided tape without being torn or crushed. Then, the gold sheet and the double-sided tape were patterned together using UV laser...

Direct mass spectrometry (MS) is an exciting strategy in bioanalysis, enabling rapid decision-making in different scenarios. Its application is usually hindered by matrix effects and the typically low concentration of the target compounds in the biofluids. In this sense, combining a previous sample preparation step minimizes or removes these shortcomings. This article describes sorptive tape-spray tandem mass spectrometry (STS-MS/MS) based on mixed-mode particles as a strategy to combine sample preparation and MS analysis in a single device...

Microneedle drug delivery has recently emerged as a clinical method, and dissolving microneedles (DMNs) offer exclusive simplicity and efficiency, compared to the other kinds of microneedles. The tips of most currently available DMNs are cone/house-shaped to result in a lower penetration force. Penetration of the needle tips into the skin relies mainly on the back tape or external pressure, and their adhesion to the skin is relatively low. In addition, only the drug in the part of tips that are pierced into the dermis can be dissolved, resulting in drug waste...

Surface-enhanced Raman scattering (SERS) has emerged as a powerful surface analytical technique that amplifies Raman scattering signals of molecules adsorbed onto metal nanostructured surfaces. The droplet reaction method has recently been employed to fabricate large-scale microring patterns of silver (Ag) nanostructures on rigid substrates, which enables sensitive detection within the ring area. However, these rigid substrates present limitations for direct on-site detection of analyte residues on irregular sample surfaces...

BACKGROUND: Endotracheal tube fixation in ventilated patients must be appropriate to ensure security during mechanical ventilation and prevent skin lesions. The incidence of endotracheal tube-caused pressure ulcers ranges from 7% to 45%. Various endotracheal tube fixations are used in intensive care units (ICUs) worldwide. By pressure exercised on the skin, these systems could lead to mucosal and skin peri-oral lesions. The main objective of this study is to evaluate the impact of the two fixation systems most commonly used in French ICUs (adhesive elastic band versus fixation cord with PolyVinyl Chloride (PVC) sheath) on the incidence of these peri-oral skin lesions...

The global pollution crisis arising from the accumulation of plastic in landfills and the environment necessitates addressing plastic waste issues. Notably, polypropylene (PP) waste accounts for 20% of total plastic waste and holds promise for hydrophobic applications in the realm of recycling. Herein, the transparent and non-transparent superhydrophobic films made from waste PP are reported. A hierarchical structure with protrusions is induced through spin-casting and thermally induced phase separation. The films had a water contact angle of 159° and could vary in thickness, strength, roughness, and hydrophobicity depending on end-user requirements...

This study explored how the human brain perceives stickiness through tactile and auditory channels, especially when presented with congruent or incongruent intensity cues. In our behavioral and functional MRI (fMRI) experiments, we presented participants with adhesive tape stimuli at two different intensities. The congruent condition involved providing stickiness stimuli with matching intensity cues in both auditory and tactile channels, whereas the incongruent condition involved cues of different intensities...

Tracheotomy is a routine surgical procedure in oral and maxillofacial surgery. After decannulation, spontaneous tracheostoma closure is usually expected. However, wound healing is often delayed, requiring 1 to 2 weeks for healing and resulting in the need for surgical closure. Although many reports have described the surgical closure of a tracheostoma, few reports have focused on the dressing methods for closure of tracheal openings after decannulation. Herein, the authors report a new tracheostoma closure method that does not rely on surgical closure or the adhesive strength of the tape...

Adhesive hydrogel holds huge potentials in biomedical applications, such as hemostasis and emergent wound management during outpatient treatment or surgery. However, most adhesive hydrogels underperform to offer robust adhesions on the wet tissue, increasing the risk of hemorrhage and reducing the fault tolerance of surgery. To address this issue, we develop a polysaccharide-based bioadhesive hydrogel tape (ACAN) consisting of dual-crosslinking of allyl cellulose (AC) and carboxymethyl chitosan (CMCS). The hygroscopicity of AC and CMCS networks enable ACAN to remove interfacial water from the tissue surface and initialize a physical crosslink instantly...

Bacteria migration at catheter insertion sites presents a serious complication (bacteraemia) with high mortality rates. One strategy to mediate bacteraemia is a physical barrier at the skin-catheter interface. Herein a colorimetric biosensor adhesive (CathoGlu) is designed and evaluated for both colorimetric detection of bacterial infection and application as a bacteria barrier. The design intent combines viscous, hydrophobic bioadhesive with an organic pH indicator (bromothymol blue). Visual observation can then distinguish healthy skin at pH = ∼5 from an infected catheter insertion site at pH = ∼8...

BACKGROUND: The adhesive elastic tape use is indicated for controlling oedema, although currently there is not the definitive evidence regarding its effectiveness. Wrist fractures are a frequent occurrence, often leading to oedema development in patients treated with forearm casts. This pilot study aims to investigate the effects of elastic tape in controlling hand oedema among patients with forearm casts for wrist fractures and the feasibility of a future randomized controlled trial...

The use of doxycycline as a sclerosing agent is well-established.(1,2,3) Given the clinical efficacy of doxycycline sclerosant therapy, we embarked upon a study to evaluate the efficacy of small-volume liquified doxycycline particularly in thick skinned rhinoplasty patients to promote re-adhesion of the nasal skin-soft tissue envelope (SSTE) thereby minimizing surgical dead space and enhancing surface contour, to improve the eventual outcome of surgery. We present 2 clinical case series using rhinodesis. All patients were treated with the same rhinodesis protocol that included conventional splinting and taping...

The incorporation of a naphthyl curing agent (NCA) can enhance the thermal stability of pressure-sensitive adhesives (PSAs). In this study, a PSA matrix was synthesized using a solution polymerization process and consisted of butyl acrylate, acrylic acid, and an ethyl acrylate within an acrylic copolymer. Benzoyl peroxide was used as an initiator during the synthesis. To facilitate the UV curing of the solvent-borne PSAs, glycidyl methacrylate was added to introduce unsaturated carbon double bonds. The resulting UV-curable acrylic PSA tapes exhibited longer holding times at high temperatures (150 °C) compared to uncross-linked PSA tapes, without leaving any residues on the substrate surface...

Traditional epidermal electrodes, typically made of silver/silver chloride (Ag/AgCl), have been widely used in various applications, including electrophysiological recordings and biosignal monitoring. However, they present limitations due to inherent material mismatches with the skin. This often results in high interface impedance, discomfort, and potential skin irritation, particularly during prolonged use or for individuals with sensitive skin. While various tissue-mimicking materials have been explored, their mechanical advantages often come at the expense of conductivity, resulting in low-quality recordings...

Low-temperature plasma treatment with atmospheric discharge with runaway electrons (DRE) was shown to be an efficient way to activate carbon fiber's (CF) surface and subsequently increase its interlayer shear strength (ILSS) values. It was demonstrated that an acceptable ILSS level was achieved after a DRE plasma treatment duration of 15 min. The treatment of CFs resulted in their surface roughness being increased and their functional groups grafting. The XPS data showed a change in the chemical composition and the formation of reactive oxygen-containing groups...

AIM: The aim of this study is to explore SC biomarkers of immune and hormonal response and skin barrier for assessment of psychological distress (PD) in HCWs. METHODS: Twenty-five female HCWs and 25 non-HCWs participated...

There is uncertainty whether postoperative application of paper tape (PT) improves scar aesthetics and reduces wound closure complications. This study aimed to review and assess the quality of applicable findings from studies investigating PT's efficacy. We queried PubMed and SCOPUS using the search terms "(("paper tape") AND (wound OR closure OR heal* OR complication OR skin OR prevent* OR scar*))." We excluded articles that were duplicates, basic science, or not clinically relevant. We assessed the level of evidence for each article using the American Society of Plastic Surgeons (ASPS) Rating Levels of Evidence and Grading Recommendations for Therapeutic Studies, ranging from I (highest) to V (lowest)...

This work used a highly flexible, sustainable polyimide tape as a substrate to deposit ductile-natured carbonaceous Ni3 N (C/Ni3 N@polyimide) material for supercapacitor application. C/Ni3 N was prepared using a co-sputtering technique, and this method also provided better adhesion of the electrode material over the substrate, which is helpful in improving bending performance. The ductile behavior of the sputter-grown electrode and the high flexibility of the polyimide tape provide ultimate flexibility to the C/Ni3 N@polyimide-based supercapacitor...
