Polydimethylsiloxanes - Based Fluorescent Probe for HS Detection in Living Cells.

The development of fluorescent probes for HS detection especially in living cells is of great significance due to its fundamental role as signal molecule. A promising scaffold for the development of such probes is polydimethylsiloxanes (PDMS), which is cost-effectiveness, non-toxicity, flexibility, and biocompatibility and easy to post-functionalize. Surprisingly, fluorescent probes for HS detection based on PDMS have not been investigated.
