Cysteine sensing application of fluorescent gold nanoclusters prepared from protein amyloid

What is it about?

Amyloid fibrils are known to be toxic and responsible for a neurodegenerative diseases. In this paper, we used amyloid fibril of fibril to synthesize highly fluorescent gold nanoclusters. Their applications in the detection of cysteine has been shown in test tube and inside live cells.

Why is it important?

We show that this type materials can be used in different applications of cellular imaging with minimum toxic effects.
