Amplifying the Macromolecular Crowding Effect Using Nanoparticles
Zaki, Ahmed; Liu, Juewen; Dave, Neeshma (American Chemical Society, 2012-01-11)The melting temperature (Tm) of DNA is affected not only by salt but also by the presence of high molecular weight (MW) solutes, such as polyethylene glycol (PEG), acting as a crowding agent. For short DNAs in a solution ... -
Dissecting the effect of anions on Hg2+ detection using a FRET based DNA probe
Kiy, Mehmet Murat; Zaki, Ahmed; Menhaj, Arsalsan Beg; Samadi, Azadeh; Liu, Juewen (Royal Society of Chemistry, 2012-08-07)Many biosensors have been developed to detect Hg2+ using thymine-rich DNA. While sensor response to various cations is often studied to demonstrate selectivity, the effect of anions has been largely overlooked. Anions may ...
