Adsorption of DNA Oligonucleotides by Titanium Dioxide Nanoparticles
Zhang, Xu; Wang, Feng; Liu, Biwu; Kelly, Erin Y.; Servos, Mark R.; Liu, Juewen (American Chemical Society, 2014-01-28)Titanium dioxide (TiO2) or titania shows great promise in detoxification and drug delivery. To reach its full potential, it is important to interface TiO2 with biomolecules to harness their molecular recognition function. ... -
Attaching DNA to Nanoceria: Regulating Oxidase Activity and Fluorescence Quenching
Pautler, Rachel; Kelly, Erin Y.; Huang, Po-Jung Jimmy; Cao, Jing; Liu, Biwu; Liu, Juewen (American Chemical Society, 2013-08-14)Cerium oxide nanoparticles (nanoceria) have recently emerged as a nanozyme with oxidase activity. In this work, we present a few important interfacial properties of nanoceria. First, the surface charge of nanoceria can be ... -
Cation-Size-Dependent DNA Adsorption Kinetics and Packing Density on Gold Nanoparticles: An Opposite Trend
Liu, Biwu; Kelly, Erin Y.; Liu, Juewen (American Chemical Society, 2014-11-11)The property of DNA is strongly influenced by counterions. Packing a dense layer of DNA onto a gold nanoparticle (AuNP) generates an interesting colloidal system with many novel physical properties such as a sharp melting ... -
Visual optical biosensors based on DNA-functionalized polyacrylamide hydrogels
Khimji, Imran; Kelly, Erin Y.; Helwa, Youssef; Hoang, Michael; Liu, Juewen (Elsevier, 2013-12-15)Biosensors are devices that can provide quantitative or semi-quantitative analytical information about target molecules, where molecular recognition is based on biomolecular interactions. In recent years, DNA has emerged ...
