Advanced Functional Materials, EarlyView.DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Electroceutical Fabric Lowers Zeta Potential and Eradicates Coronavirus Infectivity upon Contact
, 2020 Coronavirus with intact infectivity attached to PPE surfaces pose significant threat to the spread of COVID-19. We tested the hypothesis that an electroceutical fabric, generating weak potential difference of 0.5V, disrupts the infectivity of coronavirus

Molecular Origins of the Zeta Potential
Langmuir, 2016 The zeta potential (ZP) is an oft-reported measure of the macroscopic charge state of solid surfaces and colloidal particles in contact with solvents. However, the origin of this readily measurable parameter has remained divorced from the molecular-level processes governing the underlying electrokinetic phenomena, which limits its usefulness.

Zeta potential changing nanoemulsions: Impact of PEG-corona on phosphate cleavage.
International journal of pharmaceutics, 2020 The aim of this study was to evaluate the impact of a PEG-corona on oily droplets of a nanoemulsion on phosphate cleavage on their surface. A PEG-free nanoemulsion composed of 60% oleic acid, 30% Capmul MCM EP and 10% Span 85 being additionally ...

Advanced Functional Materials, EarlyView.Multianalyte, real‐time monitoring of bioprinted scaffolds remains challenging. Phosphorescence‐lifetime–based, optically responsive microparticles are embedded in diverse printable hydrogels (κ‐carrageenan, GelMA, PEGDA) to form biomaterial inks that report oxygen, glucose, lactate, and temperature.
