Findings from Shanghai Normal University in Nanotechnology Reported (A Visual Raman Nano-Delivery System Based on Thiophene Polymer for Microtumor Detection).

A recent report from Shanghai Normal University in China discusses the development of a visual Raman nano-delivery system (NS) based on a thiophene polymer for microtumor detection. The researchers introduce a donor-acceptor (D-A)-structured thiophene-based polymer called PBDB-T, which exhibits strong pre-resonant Raman enhancement and avoids fluorescence interference. The PBDB-T NS enables the diagnosis of microtumor regions and deeper tumor tissues, with potential applications in visual drug delivery systems. This research opens up possibilities for targeted drug delivery methods tailored to specific regions. [Extracted from the article]
