Simultaneous Detection of Multi-DNAs and Antigens Based on Self-Assembly of Quantum Dots and Carbon Nanotubes

Preparation and applications of self-assembled natural and synthetic nanostructures

“…This technique has multiple applications in the detection of ultrasensitive antigens, antibodies, DNAs of pathogens, photoelectrical biosensors, and molecular imaging (Sepulveda et al, 2009;Algar et al, 2010;Medintz et al, 2003;Pumera et al, 2007;Sassolas et al, 2008;Yang et al, 2010;Alivisatos, 2003;Cui et al, 2008;Huang and Cui et al, 2011;Xin et al, 2008;Zijlstra and Orrit, 2011). In this, the CNT and QD probes are functionalized with alkyloligonucleotide and on addition of requisite oligonucleotide a nanohybrid structure is formed by self-assembly.…”
