Fluorescent EGTA-derived carbon dots for turn on–off–on detection of Fe3+ and ascorbic acid via hydrothermal synthesis and cellular imaging

Scientific Reports
We present a novel, one-step hydrothermal synthesis of carbon dots (CDs) with intense blue fluorescence and a remarkably high quantum yield of 50%, using ethylene glycol tetraacetic acid (EGTA) as a single precursor eliminating the need for additional ...

Fluorine alopecia [PDF]

Epidemiology and Infection, 1946
A high proportion of young men in this country suffer from premature baldness. Alopecia is not a disease entity but one of the outstanding features of chronic fluorine poisoning (fluorosis). It is frequently associated with dystrophies of other organs of ectodermal origin, namely, those of the skin and its other appendages, the teeth and nails.

Biomimetic synthesis of vesicular covalent organic frameworks by gemini surfactants for in-situ enzyme cascade immobilization

Nature Communications
In nature, enzymes in biofilms often lack robustness and chemical functionality. Covalent organic frameworks (COFs) have emerged as a robust platform for enzyme immobilization, but mimicking biofilm structures for in-situ enzyme immobilization remains ...
