Serpe, Michael J., Islam, Molla R.
In this submission we fabricated a humidity-responsive polymer-based actuator by layering negatively charged poly(N-isopropylacrylamide)-co-acrylic acid microgels and positively charged poly(diallyldimethyl ammonium chloride) on top of a flexible plastic substrate. We show that the extent of the...

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...

Islam, Molla R., Lu, Zhenzhen, Li, Xue, Sarker, Avijeet K., Hu, Liang, Choi, Paul, Li, Xi, Hakobyan, Narek, Serpe, Michael J.
Stimuli-responsive polymers are capable of translating changes in their local environment to changes in their chemical and/or physical properties. This ability allows stimuli-responsive polymers to be used for a wide range of applications. In this review, we highlight the analytical applications...

Temperature and pH responsive semi-interpenetrating network (semi-IPN) hydrogel-based bilayer actuators were fabricated by generating a poly(N-isopropylacrylamide) (pNIPAm)-based hydrogel in the presence of positively charged polyelectrolyte poly(diallyldimethylammonium chloride) (pDADMAC) on a...

Serpe, Michael J., Wong, Ka Y., Ahiabu, Andrews, Gao, Yongfeng
Systems composed of a poly(N-isopropylacrylamide)-co-acrylic acid (pNIPAm-co-AAc) microgels (AAc-MG) and poly(N-isopropylacrylamide-3-(acrylamido)phenylboronic acid) (pNIPAm-co-APBA) microgels (APBA-MG) were used to sequentially release small molecules to a system in a controlled and triggered...
