A novel turn-off fluorescent nanoprobe for DEQ was constructed based on DNA-AgNCs, with the turn-off fluorescence being due to electron transfer from the DNA-AgNCs to DEQ.
The synthesis of pentacyclic 6H,13H-pyrazino[1,2-a;4,5-a′]diindole analogues and their evaluation for antiplasmodial activity against 3D7 and Dd2 Plasmodium falciparum strains are reported.
The above natural products have exhibited unique anti-leishmania activity to varying degrees after structural modification.
Gold nanostars with 4-mercaptobenzoic acid as SERS nanotags show high biostability in cell culture media, with/without BSA precoating. SERS imaging reveals higher uptake by immune vs cancer cells; with protein precoating showing little effect.
A new class of D–π–A teraryl-based AIEgen 6a was designed and synthesized for selective staining of intracellular lipid droplets.
