Li group published article on Journal of Materials Chemistry B about a study of organosilicon modification enhanced the stability of black phosphorus nanosheets at ambient conditions

Thanks to its tunable direct-bandgap, high charge-carrier mobility and unique in-plane anisotropic structure, black phosphorus (BP) has become a rising star of post-graphene two-dimensional (2D) nanomaterials. However, BP is unstable in the ambient conditions which largely limits its application....

Li group published article on Journal of Materials Chemistry B about a study of black phosphorus quantum dot based novel siRNA delivery systems in human pluripotent teratoma PA-1 cells

As a novel semiconducting material, the inherent, direct, and appreciable band gap endows BP with preferable optical and electronic properties other than graphene and transition metal dichalcogenides. In addition, bio-related applications with equal importance also attract great attention thanks...

Li group published article on Bioconjugate Chemistry about a study of reversible and versatile on-tether modification of chiral center-induced helical peptides

Modification of the cross-linker of constrained peptides has recently received considerable attention. Here, we present a versatile approach to modify the cross-linking tether of chiral center-induced helical (CIH) peptides via S-alkylation reac-tion. The alkylation process displayed high conversion efficiency,...

Li group published article on Synlett about a study of lipid–cell-penetrating-peptide conjugates as effective delivery systems

A lipid–cell-penetrating-peptide (CPP) conjugate was designed to deliver cargoes with poor cellular permeability, including peptides or small-molecule therapeutics, into cells. The lipid–CPP conjugate facilitated the cellular uptake of cargoes noncovalently through an ATP-dependent micropinocytosis mechanism. This delivery system is...

Li group published article on The Chemical Record about a review of Thioether-Derived Macrocycle for Peptide Secondary Structure Fixation

Recently, we developed methods to stabilize peptides into various secondary structures, including a-helix, type III turn and b-hairpin via proper thioether based macrocyclization. These conformationally constrained peptidomimetics confer enhanced biophysical properties and provide a valuable avenue towards clinically-relevant therapeutic...
