Bioinspired Stabilization of Fluorescent Au@SiO2 Tracers for Multimodal Biological Imaging
Advanced Functional Materials, EarlyView.This study demonstrates a bioinspired stabilization strategy for fluorescent gold‐silica nanoparticles. Inspired by natural biosilica maturation, high‐temperature calcination transforms the silica shells, preventing dissolution in cell culture media and intracellular environments.

The L-amino acid oxidase of Neurospora [PDF]
, 1951 In 1944 one of us described a D-amino acid oxidase in extracts of Neurospora crassa (1). Except for slight activity against L-glutamate, no oxidation of L-amino acids was observed.
