In vivo validation
Research gap analysis derived from 2 biology papers in our local library.
The gap
Most studies lack in vivo evaluation of their proposed biomaterials, drug delivery systems, and therapeutic agents under physiological conditions.
Consensus across the literature
The papers collectively establish the need for in vivo testing but leave open the specific methods and populations required.
Research trend
Emerging — attention growing, methods still coalescing.
