Provided herein is a biomaterial comprising a sensor system comprising a donor fluorophore linked to a target binding moiety (TBM) and an acceptor molecule linked to a TBM, wherein, when the TBM linked to the donor fluorophore and the TBM linked to the acceptor molecule binds to a target, a resonance energy transfer (RET; e.g., Forster (or Fluorescence) resonance energy transfer (FRET), bioluminescent resonance energy transfer (BRET), chemiluminescent resonance energy transfer (CRET), or a combination thereof) from the donor fluorophore to the acceptor molecule occurs and a detectable signal is produced. An medical device, e.g., an implant, comprising the presently disclosed biomaterial comprising a sensor system is further provided. Related medical devices and solid supports are furthermore provided herein. Use of the biomaterials and medical devices in methods of determining a level of expression of a gene, an RNA, or a protein, is additionally provided. |
