An ultrasensitive colorimetric aptasensor has been proposed to detect streptomycin(STR)with porous SiO2 micro beads labeled with enzyme linked polymer(PowerVisionTM reagents,PV)probes and exonuclease-
T-cell receptor-CD3 complex(TCR)is one of the most versatile signaling machines,which contains in total twelve different phosphorylatable tyrosines from six immunoreceptor tyrosine-based activation mo
A novel ratio fluorescence sensor for Pb2+detection has been synthesized by encapsulating rhodamine-B with a strong fluoresence into the zeolitic imidazolate materials(ZIF-8).The carboxyl groups and n
