Temperature is a critical extrinsic physical parameter that determines cell fate. Hyperthermia therapy has become an efficient treatment for tumor ablation. To understand the response of tumor cells under thermal shocks, we present a paper-based photothermal array that can be conveniently coupled with commercial 96-well cell culture plates. This paper chip device was fabricated in one step using Parafilm® and Kimwipers® based on a heat lamination strategy. Liquid was completely adsorbed and confined within the cellulose fibres of hydrophilic regions...

This review outlines recently developed Prussian blue nanoparticle (PB NPs)-based multimodal imaging-guided chemo-photothermal strategies for cancer diagnosis and treatment in order to provide insight into the future of the field. The primary limitation of existing therapeutics is the lack of selectivity in drug delivery: they target healthy and cancerous cells alike. In this paper, we provide a thorough review of diverse synthetic and surface engineering techniques for PB NP fabrication. We have elucidated the various targeting approaches employed to deliver the therapeutic and imaging ligands into the tumor area, and outlined methods for enhancement of the tumor ablative ability of the NPS, including several important combinatorial approaches...

In situ monitoring of the photothermal (PT) effect at the cellular level is of great importance in the photothermal (PT) treatment of cancer. Herein, we report a class of DNA-templated gold nanoparticle (GNP)-quantum dot (QD) complexes (GQC) for PT sensing in solution and in cancer cells in vitro. Specifically, the QD photoluminescence (PL) could be activated at elevated temperature with a wide thermo-responsive range between 45 °C and 70 °C, which fits the temperature threshold for effective cancer cell ablation...

Prussian blue (PB) is a coordination polymer studied since the early 18th century, historically known as a pigment. PB can be prepared in colloidal form with a straightforward synthesis. It has a strong charge-transfer absorption centered at ~700 nm, with a large tail in the Near-IR range. Irradiation of this band results in thermal relaxation and can be exploited to generate a local hyperthermia by irradiating in the so-called bio-transparent Near-IR window. PB nanoparticles are fully biocompatible (PB has already been approved by FDA) and biodegradable, this making them ideal candidates for in vivo use...

Design and development of photosensitizers that can efficiently convert energy of near-infrared (NIR) laser irradiation are of major importance for cancer photoassisted therapeutics. Herein, for the first time, it is demonstrated that Prussian blue (PB), a classic coordination compound, can act as a novel photosensitizer with efficient generation of singlet oxygen and excellent photothermal conversion via NIR photoirradiation-induced energy transfer. After modification with hyaluronic acid (HA), the as-prepared HA-modified PB nanocubes (HA@PB) are highly dispersible in aqueous and physiological solutions, as well as show excellent photothermal/photodynamic activities under NIR (808 nm) photoexcitation...

A thermal "window" of immunogenic cell death (ICD) elicited by nanoparticle-based photothermal therapy (PTT) in an animal model of neuroblastoma is described. In studies using Prussian blue nanoparticles to administer photothermal therapy (PBNP-PTT) to established localized tumors in the neuroblastoma model, it is observed that PBNP-PTT conforms to the "more is better" paradigm, wherein higher doses of PBNP-PTT generates higher cell/local heating and thereby more cell death, and consequently improved animal survival...

Tumor hypoxia is one of the major challenges for the treatment of tumors, as it may negatively affect the efficacy of various anticancer modalities. In this study, a tumor-targeted redox-responsive composite biocatalyst is designed and fabricated, which may combine tumor starvation therapy and low-temperature photothermal therapy for the treatment of oxygen-deprived tumors. The nanosystem was prepared by loading porous hollow Prussian Blue nanoparticles (PHPBNs) with glucose oxidase (GOx) and then coating their surface with hyaluronic acid (HA) via redox-cleavable linkage, therefore allowing the nanocarrier to bind specifically with CD44-overexpressing tumor cells while also exerting control over the cargo release profile...

Here we demonstrate for the first time that Mn2+ -doped Prussian blue nanoparticles of c.a. 70 nm act as effective agents for photothermal therapy under two-photon excitation with an almost total eradication of malignant cells (97 and 98%) at a concentration of 100 μg mL-1 24 h after NIR excitation. This effect combined with interesting longitudinal NMR relaxivity values offer new perspectives for effective imaging and cancer treatment.

Because of the nontargeting release of anticancer drugs, conventional chemotherapy results in serious side effects and poor therapeutic outcomes. In addition, hypoxia situation in the tumor microenvironment also promotes the growth and metastasis of tumors. Multifunctional nanocarriers with stimuli-activation and hypoxia-relieving properties can help overcome some of these limitations. In this study, we have constructed a nanocarrier which is named PBMn-DOX@RBC. A Prussian blue/manganese dioxide (PBMn) nanoparticle is used as an oxygen precursor or catalyzer for H2 O2 activation, and a red blood cell (RBC) membrane is used to increase the loading capacity of doxorubicin (DOX) and prolong the circulation time in vivo...

Herein, we demonstrate a coating-etching strategy to directly synthesize hollow Prussian blue (PB) nanocubes with well-dispersed Ag nanoparticles (denoted as Ag-HPB). The method is accomplished by introduction of PB precursors, K3 Fe(CN)6 and Fe3+ into a reaction system containing AgNO3 and ascorbic acid, in which a series reactions contain formation of Ag nanoparticles, coating of PB on the nanoparticles, and diffusion of Ag into the PB frameworks occur. The strategy for preparation of the hollow structured Ag-HPB is intrinsically simple and does not require pre-preparation of any sacrificial templates or toxic etching agents...

The study reports a biocompatible smart drug delivery system based on a doxorubicin (DOX) blending phase-change material of 1-pentadecanol loaded hollow magnetic Prussian blue nanoparticles, resulting in HMNP-PB@Pent@DOX. The system possesses concentration-dependent high thermogenesis (>50 °C) when applying a near-infrared (NIR) laser irradiation only for 5 min. Furthermore, the system realizes near "zero release" of drug and is efficiently triggered by NIR for drug delivery in an "on" and "off" manner, thus inducing cell apoptosis in vitro and in vivo...

Multimodal imaging-guided diagnosis and therapy has been highlighted in the area of theranostic nanomaterials. To provide more suitable theranostic candidates, Prussian blue (PB)/manganese dioxide (MnO2 ) hybrid nanoparticles (PBMn) smaller than 50 nm are prepared by a one-pot method. MnO2 , which is reduced from KMnO4 , not only controls the particle size, the optical properties, and the transverse relaxation rate (r2 ) of PB but also enhances the catalysis efficacy of PB to H2 O2 for oxygen generation. PBMn can serve as a photoacoustic imaging (PAI) and longitudinal relaxation (T1 ) mode magnetic resonance imaging contrast agent (14 times and 1...

Prussian blue (PB) has been used as a photothermal conversion agent to generate heat to induce localized damage to tumor. However, its therapeutic efficiency is far from satisfactory. One of the major obstacles is that the maximum NIR absorption peak of PB within 690-720 nm cannot be optimized near the wavelength of the laser to enhance its therapeutic efficiency. Herein, we report that the integration of Gd3+ into PB nanocrystals (GPB NCs) enables PB with tunable localized surface plasmon resonances (LSPRs) from 710 to 910 nm, achieving the maximum NIR peak near the wavelength of the laser...
