Harnessing platelets as functional vectors for contrast enhanced ultrasound imaging and fluorescence imaging.

The recent progress in the development of highly biocompatible nanoplatforms mostly encompasses the use of biological excipients such as red blood cells, cancer cell membranes, and also platelets. Such specialized vectors, if mimicked correctly, have intrinsic ability to navigate through the biological system and perform their intended action without eliciting any cascade of inflammatory processes. Naturally, platelets have been found to accumulate in the wound sites and also interact with circulating tumor cells (CTCs).
