Biochem/physiol Actions

18:1 TAP (DOTAP) is a cationic lipid structure, used for in vitro and in vivo nucleic acid and protein delivery. The lipid composition and cell type affects the transfection potential of DOTAP(1,2-dioleoyl-3-trimethylammonium-propane). 18:1 TAP (DOTAP) mediates gene knockdown technique in hematopoietic stem cells (HSCs).

Aggregation-induced emission (AIE) is a powerful method to produce fluorescence for a diverse range of applications. While most previous work induced aggregation by change of solvent, ionic strength, pH, or self-assembly, we herein explored adsorption-induced aggregation using 4,4'-(hydrazine-1,2-diylidene bis(methanylylidene)) bis(3-hydroxybenzoic
