Negative Chemotaxis of Urease‐Functionalized Polymeric Microcapsules

open access: yesSmall, EarlyView.
Urease‐functionalized PLGA microcapsules exhibit negative chemotaxis in urea gradients, migrating from high to low substrate concentrations. Increasing gradients enhance chemotaxis until a plateau, while increasing average substrate concentration in a fixed gradient reverses chemotactic behavior.

Bias Polarity Switching (BiPS): A Transient Method for Probing Interfacial Carrier Dynamics

open access: yesSmall Methods, EarlyView.
Bias Polarity Switching combines optical excitation with rapid bias reversal to probe near‐interface carrier accumulation, trapping, detrapping, and extraction together with bulk carrier transport. The method provides access to defect kinetics and contact‐related transport processes, offering a complementary approach for investigating semiconductor ...
