Regenerable DNA-Functionalized Hydrogels for Ultrasensitive, Instrument-Free Mercury(II) Detection and Removal in Water
(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 ...
DNA-Functionalized Monolithic Hydrogels and Gold Nanoparticles for Colorimetric DNA Detection
(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 ...
Assembly of DNA-Functionalized Nanoparticles in Alcoholic Solvents Reveals Opposite Thermodynamic and Kinetic Trends for DNA Hybridization
(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 ...
Flow Cytometry-Assisted Detection of Adenosine in Serum with an Immobilized Aptamer Sensor
(American Chemical Society, 2010-05-15)
Aptamers are single-stranded nucleic acids that can selectively bind to essentially any molecule of choice. Because of their high stability, low cost, ease of modification, and availability through selection, aptamers hold ...
Fast Molecular Beacon Hybridization in Organic Solvents with Improved Target Specificity
(American Chemical Society, 2010-12-02)
DNA hybridization is of tremendous importance in biology, bionanotechnology, and biophysics. Molecular beacons are engineered DNA hairpins with a fluorophore and a quencher labeled on each of the two ends. A target DNA can ...
