Optical biosensors and micromotors that can sense and actuate biological environments are considered promising theranostic devices because of their high spatial resolution and flexibility. Advancing the field from synthetic sensors to living materials - which often can be incompatible with biological systems - researchers have assembled living biosensors and micromotors using an in vivo red blood cell (RBC) waveguide for applications in pH sensing and particle transport. This living biosensor ca... nanowerk · 1 month
