Assembly of DNA-Functionalized Gold Nanoparticles with Gaps and Overhangs in Linker DNA
Smith, Brendan D.; Dave, Neeshma; Huang, Po-Jung Jimmy; Liu, Juewen (American Chemical Society, 2011-04-28)DNA-directed assembly of gold nanoparticles (AuNPs) has been extensively studied because of its important applications in analytical chemistry, materials science, and nanomedicine. In a typical system, two DNA-functionalized ... -
Assembly of DNA-Functionalized Nanoparticles in Alcoholic Solvents Reveals Opposite Thermodynamic and Kinetic Trends for DNA Hybridization
Smith, Brendan D.; Liu, Juewen (American Chemical Society, 2010-05-12)DNA has been a key molecule in biotechnology and nanotechnology. To date, the majority of the experiments involving DNA have been performed in aqueous solutions, which may be related to the perception that DNA hybridization ... -
DNA-Functionalized Monolithic Hydrogels and Gold Nanoparticles for Colorimetric DNA Detection
Baeissa, Aifan; Dave, Neeshma; Smith, Brendan D.; Liu, Juewen (American Chemical Society, 2010-12-22)Highly sensitive and selective DNA detection plays a central role in many fields of research, and various assay platforms have been developed. Compared to homogeneous DNA detection, surface-immobilized probes allow washing ... -
Exploring the thermal stability of DNA-linked gold nanoparticles in ionic liquids and molecular solvents
Smith, Brendan D.; Liu, Juewen; Menhaj, Arsalsan Beg (Royal Society of Chemistry, 2012-11-01)While water is the most commonly used solvent for DNA, many co-solvents have been added for various applications. Ionic liquids (ILs) are molten salts at around room temperature. ILs have been tested as a green solvent for ... -
Regenerable DNA-Functionalized Hydrogels for Ultrasensitive, Instrument-Free Mercury(II) Detection and Removal in Water
Dave, Neeshma; Chan, Michelle Y.; Huang, Po-Jung Jimmy; Smith, Brendan D.; Liu, Juewen (American Chemical Society, 2010-09-15)Mercury is a highly toxic environmental pollutant with bioaccumulative properties. Therefore, new materials are required to not only detect but also effectively remove mercury from environmental sources such as water. We ...
