Novel insulin thiomer nanoparticles: in vivo evaluation of an oral drug delivery system.

abstract：:The single-coat protein (CP) of bacteriophage Qβ self-assembles into T = 3 icosahedral virus-like particles (VLPs), of interest for a wide range of applications. These VLPs are very stable, but identification of the specific molecular determinants of this stability is lacking. To investigate these determinants along w...
