Researchers have developed a way to achieve an ultra-high bioelectric signal from human embryonic stem cells using direct current-voltage measurements facilitated by few-layered 2D molybdenum disulfide sheets. This method, which produces cell signals 2 orders of magnitude higher than previous electrical-based detection methods, paves the way for the development of a broadly applicable, fast, and damage-free stem cell detection method capable of identifying pluripotency with virtually any complementary metal-oxide-semiconductor circuits.

By employing 3D scaffolds with both aligned nanofibers and aligned interconnected macrochannels, researchers have taken a nanotechnology-based tissue engineering approach to accelerate the regeneration and repair of damaged tissues at the wound site by directing cells and tissues to grow towards the target site. Their hope is that this leads to the development of affordable and functional biodegradable wound dressings for accelerated healing of chronic skin wounds by promoting regeneration of local tissues.

Scientists propose a novel tumor treatment strategy for simultaneous ablating tumor and inhibiting infection by using specially designed biodegradable metal-organic frameworks (MOFs). The strategy of simultaneous eradicating tumor tissue and inhibiting infection can inspire the researchers with novel progressing technologies for tumor therapy. This novel strategy opens the door for developing the nanomaterials that are sensitive to microwave irradiation and inhibiting infection to achieve noninvasive combined treatment in clinical practice.

Research on micro- and nanomachines has advanced from the observation and understanding of basic motion behavior to the constantly improving capabilities of performing complex tasks. This ranges from interaction with bacteria to propulsion based on cells and in vivo medical applications. A review looks at the applications of micro- and nanomachines in living biosystems from two aspects: the interaction of micro/nanomachines with other microscopic organisms or biological units, and the efforts toward application of micro/nanomachines in human body.

Programmable nucleic acid nanoparticle (NANP) technology is a relatively new field that has already given rise to a host of self-assembling nucleic acid nanoparticles that are increasingly viewed as promising biological materials for medical applications. Programmable self-assembling NANPs are amenable to chemical modifications, control over functionalization, and consistent batch-to-batch formulation. Researchers present the first detailed and systematic study that involved 25 most representative NANPs, originally designed by different groups, screened for the induction of 29 different cytokines.

Cell membrane coating is a platform technology that presents a facile top-down method for designing nanocarriers with surfaces that directly replicate the highly complex functionalities necessary for effective biointerfacing. This new class of biomimetic nanoparticles combines the advantages of both natural and artificial nanomaterials. Cell membrane-coated nanoparticles are characterized by a synthetic nanoparticulate core cloaked by a layer of natural cell membrane.

Drug abuse and dependence/addiction are complex disorders that are regulated by a wide range of interacting networks of genes and pathways that control a variety of phenotypes. Therefore, both identification of the at-risk population and treatment of the addiction disorders are strongly reliant on the development of new and innovative approaches for understanding the mechanisms underlying drug dependency and addiction. There are potential capacities of nanotechnology for the field of drug dependency and addiction.
