Boosting Biodetection Signals via Photopolymerization: Strategies for Photocatalyst Amplification
Photopolymerization-based signal amplification (PBA) is a method to enhance biodetection signals by coupling molecular recognition events with photocatalyst labels (eosin Y) and amplifying through visible light-initiated free radical polymerization. Leveraging inherent amplification in the radical …
