Microgel-based etalon coated quartz crystal microbalances for detecting solution pH: The effect of Au overlayer thickness
Download2013-01-01
Islam, Molla R., Johnson, Kai C. C., Serpe, Michael J.
Poly (N-isopropylacrylamide)-co-acrylic acid (pNIPAm-co-AAc) microgels were “painted” on the Au electrode of a quartz crystal microbalance (QCM). Another Au layer (overlayer) was subsequently deposited on the microgel layer. This structure is known as a microgel-based etalon. These devices have...

Polymer-based devices for the label-free detection of DNA in solution: low DNA concentrations yield large signals
Download2014-01-01
Islam, Molla R., Serpe, Michael J.
Poly (N-isopropylacrylamide-co-N-(3-aminopropyl) methacrylamide hydrochloride) microgel-based optical devices (etalons) have been shown to change their optical properties in the presence of single-stranded DNA. We hypothesize that this is due to the negatively charged DNA penetrating through the...
