Physiological processes such as metabolism, cell apoptosis and immune responses, must be strictly regulated to maintain their homeostasis and achieve their normal physiological functions. The speed with which bio-molecular homeostatic regulation occurs directly determines the ability of an organism to adapt to conditional changes. To produce a quick-responsive regulatory system that can be easi...

With the advent of nanobiotechnology, there will be an increase in the interaction between engineered nanomaterials and biomolecules. Nanoconjugates with cells, organelles, and intracellular structures containing DNA, RNA, and proteins establish sequences of nano-bio boundaries that depend on several intricate complex biophysicochemical reactions. Given the complexity of these interactions, and...

Using molecular dynamics simulations, we investigated an integrated bio-nano interface consisting of a β-sheet protein stacked onto graphene. We found that the stacking assembly of the model protein on graphene could be controlled by water molecules. The interlayer water filled within interstices of the bio-nano interface could suppress the molecular vibration of surface groups on protein, and ...

We report a unique approach in which living cells direct their integration into 3D solid-state nanostructures. Yeast cells deposited on a weakly condensed lipid/silica thin film mesophase actively reconstruct the surface to create a fully 3D bio/nano interface, composed of localized lipid bilayers enveloped by a lipid/silica mesophase, through a self-catalyzed silica condensation process. Remar...

Bio-nano interactions can be defined as the study of interactions between nanoscale entities and biological systems such as, but not limited to, peptides, proteins, lipids, DNA and other biomolecules, cells and cellular receptors and organisms including humans. Studying bio-nano interactions is particularly useful for understanding engineered materials that have at least one dimension in the na...

A new kind of bio-nanocomposite photoelectrode was fabricated through direct immobilization of the bacterial photosynthetic reaction center (RC) proteins on a nanocrystalline TiO2 matrix prepared by anodic electrodeposition. The near-infrared (NIR)visible absorption and fluorescence emission spectra displayed that structure and activity of the RC remained unaltered on the nano-TiO2 film surface...

This paper discuss about the critical review on design of carbon nanotube based MEMS piezoresistive pressure sensors, use of different types of carbon nanotubes such as multi-walled carbon nanotubes (MWCNTs), single-walled carbon nanotubes (SWNTs) and vertically aligned carbon nanotubes (VANTs), sensing mechanism, applications, etc. The structural deformation of the piezoresistive nano structur...

Abstract Nano-kirigami method enables rich diversity of structural geometries that significantly broaden the functionalities optical micro/nano-devices. However, methodologies various nano-kirigami are still limited and as a result, chiral structure has yet been pushed to limit for operation at visible wavelength region. Here, merits strategies comprehensively explored bio-inspired nano-cilia m...
