Semiconductor Quantum Dots as Multicolor and Ultrasensitive Biological Labels

Aqueous Near‐Infrared Fluorescent Composites Based on Apoferritin‐Encapsulated PbS Quantum Dots

“…The use of bioinorganic conjugates -QDs/protein systems -could overcome this problem and therefore represent an attractive tool as a novel method for use as bioactive fluorescent probes in sensing, imaging, immunoassays, and other diagnostics applications. [19,59,[78][79][80][81][82][83][84][85][86][87] In 1998, two research groups, Alivisatos et al [89] and Nie et al [56], reported the first use of quantum dots nanocrystals to label single molecules during living-cell assays and this topic is now being intensively investigated.…”

Organic and Inorganic Nanoparticle Hybrids

“…The two-step coupling procedure in Figure describes the chemical pathway using capped SWCNTs and organic soluble ZnS capped CdSe QDs as the starting materials. Selective oxidation of CNTs after fractionation produces hollow ends with carboxyl groups, and functionalizing QDs with mercaptoacetic acid (MAA) achieves water soluble building blocks for viral assembly 2 Chemical synthesis of virus networks with inorganic nanoparticles in reaction schemes FHV−CNT (A) and CPMV−QD (B).…”
