Carbon fiber electrodes may enable better long-term brain implants, minimizing the tissue response commonly seen with silicon-based electrodes. The small diameter fiber may enable high-channel count brain-machine interfaces capable of reproducing dexterous movements. Past carbon fiber electrodes exhibited both high

Introduction of Terminal Azide and Alkyne Functionalities in Polymers

Click chemistry, and the copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) in particular, is a powerful new synthetic tool in polymer chemistry and material science.

Degradable Poly(ethylene glycol) Hydrogels for 2D and 3D Cell Culture

Progress in biotechnology fields such as tissue engineering and drug delivery is accompanied by an increasing demand for diverse functional biomaterials. One class of biomaterials that has been the subject of intense research interest is hydrogels, because they closely mimic the natural environment of cells, both chemically and physically and therefore can be used as support to grow cells. This article specifically discusses poly(ethylene glycol) (PEG) hydrogels, which are good for biological applications because they do not generally elicit an immune response. PEGs offer a readily available, easy to modify polymer for widespread use in hydrogel fabrication, including 2D and 3D scaffold for tissue culture. The degradable linkages also enable a variety of applications for release of therapeutic agents.
