Bio-nano interface and environment: A critical review

Chemistry at the nano-bio interface.

The interface of biology and inorganic materials represents one of the fastest growing and most promising areas of nanotechnology. The fifth issue of JACS Select contains 22 Communications and Articles from 2008 and early 2009 that illustrate the breadth and creative energy of this young field. Although the use of colloidal particles of metals and semiconductors as pigments dates back many cent...

An ultra-thin PDMS membrane as a bio/micro-nano interface: fabrication and characterization.

We report a method for making ultra-thin PDMS membrane devices. Freely suspended membranes as thin as 70 nm have been fabricated. Bulging tests were performed with a custom built fluidic cell to characterize large circular membranes. The fluidic cell allows the media (such as air or water) to wet one side of the membrane while maintaining the other side dry. Pressure was applied to the membrane...

Nonylphenol in the Environment : A Critical Review

Nonylphenol (NP), an anaerobic breakdown product of a widely used nonionic surfactant nonylphenol ethoxylate (NPEO), is currently of environmental concern because of its toxicity, estrogenic properties and widespread contamination. Nonylphenol has been detected in surface and ground water, sediments, aquatic organisms, wastewater effluent, air, and human food. Although concentrations of NP are ...

ERRATUM: Interlayer Water Regulates the Bio-nano Interface of a β-sheet Protein stacking on Graphene

Optimization of Bio-Nano Interface Using Gold Nanostructures as a Model Nanoparticle System

Better knowledge of interface between nanotechnology and biology will lead to advanced biomedical tools for imaging and therapeutics. In this review, recent progress in the understanding of how size, shape, and surface properties of nanoparticles (NPs) affect intracellular uptake, transport, and processing of NPs will be discussed. Gold NPs are used as a model system in this regard since their ...
