Experiments have shown that DNA can be sequenced using an electrolytic cell with a nanopore and an exonuclease enzyme in the cis chamber that cleaves the leading mononucleotide in a strand of DNA. The base therein can be identified with an accuracy of 80-90% by the level of the current blockade caused in the pore; a biological adapter inside slows down the cleaved mononucleotide and lowers the detection bandwidth required. In this approach, which has been mathematically modeled, analyzed, and simulated, mononucleotides are likely to be lost to diffusion or enter the pore out of order...

Yi Ming, Hui-Min Li, Ze-Jun Ding
Thermal rectification and negative differential thermal conductance were realized in harmonic chains in this work. We used the generalized Caldeira-Leggett model to study the heat flow. In contrast to most previous studies considering only the linear system-bath coupling, we considered the nonlinear system-bath coupling based on recent experiment [Eichler et al., Nat. Nanotech. 6, 339 (2011)]. When the linear coupling constant is weak, the multiphonon processes induced by the nonlinear coupling allow more phonons transport across the system-bath interface and hence the heat current is enhanced...

An overview is provided of the challenges involved in building computer-aided diagnosis systems capable of precise medical diagnostics based on integration and interpretation of data from different sources and formats. The availability of massive amounts of data and computational methods associated with the Big Data paradigm has brought hope that such systems may soon be available in routine clinical practices, which is not the case today. We focus on visual and machine learning analysis of medical data acquired with varied nanotech-based techniques and on methods for Big Data infrastructure...

BACKGROUND: The development and progression of atherosclerosis is known to occur at a sluggish pace and the lesions remain concealed for a long duration before the factual situation of the complex atherosclerotic etiology affecting various organ gets apprehended. The root cause mainly involves an imbalance or malfunction of the cholesterol metabolizing pathway. The till date therapeutic alternatives include oral hypo-lipidemic agents along with advances made in biotechnology/tissue engineering and surgical procedures for management purpose...

Sustainable societal and economic development relies on novel nanotechnologies that offer maximum efficiency at minimal environmental cost. Yet, it is very challenging to apply green chemistry approaches across the entire life cycle of nanotech products, from design and nanomaterial synthesis to utilization and disposal. Recently, novel, efficient methods based on nonequilibrium reactive plasma chemistries that minimize the process steps and dramatically reduce the use of expensive and hazardous reagents have been applied to low-cost natural and waste sources to produce value-added nanomaterials with a wide range of applications...

Nanotechnology is a promising, novel field of technological development. There is great potential in research and clinical applications for neurological diseases. Here we chronicle the inception of nanotechnology, discuss its integration with neurology, and highlight the challenges in current application. Some of the problems involving practical use of neuronanotechnology are direct biological toxicity, visualization of the nanodevice, and the short life expectancy of nanomachinery. Neuron cell therapy is an upcoming field for the treatment of challenging problems in neurology...

The ongoing nanotech revolution has the potential to transform diagnostic and therapeutic methods. Stimuli-triggered nanotherapies based on remotely activated agents have become attractive alternatives to conventional chemotherapy. Herein, we designed an optimized smart nanoplatform based on dually loaded hybrid liposomes to achieve enhanced tumor therapy. The aqueous core was highly loaded with iron oxide nanoparticles, while the lipid bilayer was supplied with a photosensitizer payload. The double cargo translated into double functionality: generation of singlet oxygen under laser excitation and heat production under alternating magnetic field stimulation, coupling photodynamic therapy (PDT) to magnetic hyperthermia (MHT)...

Nanodiamond application in biotechnological and medical fields is nowadays in continuous progress. In fact, biocompatibility, reduced dimensions and high surface chemical interaction are specific features that make nanodiamonds perfect intracellular carriers of bioactive compounds. By confocal microscopy, we confirmed that nanodiamonds were able to penetrate in cell cytoplasm but we also demonstrated how they remained embedded in nuclear membrane just exposing some little portions into nuclear area, definitively clarifying this topic...

More than three decades since its discovery, HIV infection remains one of the most aggressive epidemics worldwide, with more than 35 million people infected. In sub-Saharan Africa, heterosexual transmissions represent nearly 80% of new infections, with 50% of these occurring in women. In an effort to stop the dramatic spread of the HIV epidemic, new preventive treatments, such as microbicides, have been developed. Nanotechnology has revolutionized this field by designing and engineering novel highly effective nano-sized materials as microbicide candidates...

We describe the propulsion mechanism of the catalytic microjet engines that are fabricated using rolled-up nanotech. Microjets have recently shown numerous potential applications in nanorobotics but currently there is a lack of an accurate theoretical model that describes the origin of the motion as well as the mechanism of self-propulsion. The geometric asymmetry of a tubular microjet leads to the development of a capillary force, which tends to propel a bubble toward the larger opening of the tube. Because of this motion in an asymmetric tube, there emerges a momentum transfer to the fluid...

The revolutionary and ubiquitous nature of nanotechnology has fetched it a considerable attention in the past few decades. Even though its enablement and application to various sectors including pharmaceutical drug development is increasing with the enormous government aided funding for nanotechnology-based products, however the parallel commercialization of these systems has not picked up a similar impetus. The technology however does address the unmet needs of pharmaceutical industry, including the reformulation of drugs to improve their solubility, bioavailability or toxicity profiles as observed from the wide array of high-quality research publications appearing in various scientific journals and magazines...

In this communication, we introduce boron nitride nanotube (BNNT)-functionalised muscle cell/microfibre mesh constructs, obtained via tissue engineering, as a three-dimensional (3D) platform to study a wireless stimulation system for electrically responsive cells and tissues. Our stimulation strategy exploits the piezoelectric behaviour of some classes of ceramic nanoparticles, such as BNNTs, able to polarize under mechanical stress, e.g. using low-frequency ultrasound (US). In the microfibre scaffolds, C2C12 myoblasts were able to differentiate into viable myotubes and to internalize BNNTs, also upon US irradiation, so as to obtain a nanotech-assisted 3D in vitro model...
