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 ... -
Distinction of Individual Lanthanide Ions with a DNAzyme Beacon Array
Huang, Po-Jung Jimmy; Vazin, Mahsa; Lin, Jennifer J.; Pautler, Rachel; Liu, Juewen (American Chemical Society, 2016-06-24)Developing chemical probes to distinguish each lanthanide ion is a long-standing challenge. Aside from its analytical applications, solving this problem will also enhance our knowledge in metal ligand design. Using in vitro ... -
The group trend of lanthanides binding to DNA and DNAzymes with a complex but symmetric pattern
Lin, Wei Ting David; Huang, Po-Jung Jimmy; Pautler, Rachel; Liu, Juewen (Royal Society of Chemistry, 2014-07-18)Using sensitized Tb3+ luminescence spectroscopy as a tool, binding of 14 lanthanides to a lanthanide-dependent DNAzyme is studied, where the binding affinity is symmetric across the series and the tightest binding occurs ... -
Parts-per-Million of Polyethylene Glycol as a Non-Interfering Blocking Agent for Homogeneous Biosensor Development
Liu, Biwu; Huang, Po-Jung Jimmy; Zhang, Xu; Wang, Feng; Pautler, Rachel; Ip, Alexander C-F.; Liu, Juewen (American Chemical Society, 2013-11-05)Many homogeneous assays are complicated by the adsorption of probe molecules by the surface of reaction vessels, which are often made of polypropylene or polystyrene-based plastics. To solve this problem, many protein and ...
