TL;DR: The traditional motivation for integrating biological components into microfabricated devices has been to create biosensors that meld the molecular recognition capabilities of biology with the signal processing capabilities of electronic devices, but a different motivation is emerging; biological components are being explored to radically change how fabrication is achieved at the micro- and nanoscales.

TL;DR: In this article, the amine-rich polysaccharide chitosan was observed to be positively charged and water soluble under mildly acidic conditions and is uncharged and insoluble under basic conditions.

TL;DR: In this paper, the amine-containing polysaccharide chitosan was used to create hydrogels using a voltage to promote the proton-consuming hydrogen evolution reaction at the cathode surface.

TL;DR: In this article, the same authors used a modified version of the tobacco mosaic virus (TMV) to pattern the virion surface of a chitosan-coated nanoparticle.

TL;DR: In this article, a fiber Bragg grating sensor was developed by etching away the cladding and part of the core of the fiber and detecting the change of Bragg wavelength due to the change in index of the surrounding medium.
