Controlled optical transition rates in nanodroplets
(IEEE, 2000)The time-resolved fluorescence measurements of 3,3′-diethyl-5,5′-dichloro-9-phenylthiacarbocyanine (DDPT) in bulk solvents and methanol-in-oil reverse micellar systems is presented which include nano-sized methanol droplets ... -
Dependence of triboelectric charging behavior on material microstructure
(American Physical Society, 2017-08-23)We demonstrate that differences in the microstructure of chemically identical materials can lead to distinct triboelectric charging behavior. Contact charging experiments are carried out between strained and unstrained ... -
Dielectric trapping of biopolymers translocating through insulating membranes
(MDPI AG, 2018)Sensitive sequencing of biopolymers by nanopore-based translocation techniques requires an extension of the time spent by the molecule in the pore. We develop an electrostatic theory of polymer translocation to show that ... -
Electrostatic effects on nanofiber formation of self-assembling peptide amphiphiles
(Elsevier, 2011)Self-assembling peptide amphiphile molecules have been of interest to various tissue engineering studies. These molecules self-assemble into nanofibers which organize into three-dimensional networks to form hydrocolloid ... -
Orientational transition and complexation of DNA with anionic membranes: weak and intermediate electrostatic coupling
(American Physical Society, 2019)We characterize the role of charge correlations in the adsorption of a short, rodlike anionic polyelectrolyte onto a similarly charged membrane. Our theory reveals two different mechanisms driving the like-charge ... -
Peptide-mediated constructs of quantum dot nanocomposites for enzymatic control of nonradiative energy transfer
(American Chemical Society, 2011)A bottom-up approach for constructing colloidal semiconductor quantum dot (QDot) nanocomposites that facilitate nonradiative Förster-type resonance energy transfer (FRET) using polyelectrolyte peptides was proposed and ... -
Theoretical modeling of polymer translocation: from the electrohydrodynamics of short polymers to the fluctuating long polymers
(MDPI AG, 2019)The theoretical formulation of driven polymer translocation through nanopores is complicated by the combination of the pore electrohydrodynamics and the nonequilibrium polymer dynamics originating from the conformational ...
