Super‐Resolution Ultrasound Based Cell Tracking With Polymeric Nanobubbles

open access: yesAdvanced Materials, EarlyView.
This study presents a super‐resolution ultrasound platform for tracking cells in vivo. Biocompatible polymeric nanobubbles are used as highly echogenic intracellular labels. Following the injection of cells and microbubbles, ultrasound localization microscopy (ULM) can dynamically match the microvascular architecture and individual cell trajectories ...

Anion Conducting States of Excitatory Amino Acid Transporters [PDF]

open access: yes, 2013
Excitatory amino acid transporters (EAATs) are secondary active, electrogenic transporters which translocate L-glutamate (glu) against its concentration gradient using the co-transport of 3 Na+, 1 H+, and the counter-transport of 1 K+ ion.

Soft Hardware, Flowing Software: Reconfigurable Microfluidics for Adaptable Chemical Computation

open access: yesAdvanced Materials, EarlyView.
A reconfigurable microfluidic platform based on soft, photo‐printable, and chemically erasable hydrogel structures printed and erased in situ is used to control flow routing, mixing, chemical patterning, and even chemical computing. Using hardware to control chemical computations decouples logic function from molecular composition, demonstrated via ...

Intimate Interaction Between Nucleic Acid and Conjugated Polymers in Organic Electrochemical Transistors Enables Ultrasensitive Biomarker Detection

open access: yesAdvanced Materials, EarlyView.
The intimate interaction between negatively charged RNA molecules and conjugated polymers in organic electrochemical transistors (OECTs) in aqueous electrolytes is investigated. It demonstrates that RNA binding reduces the volumetric capacitance of the polymer channel, enabling the development of an ultrasensitive biosensing platform capable of ...

MOCVD‐Grown MoS2 Wafers as a Transfer‐Free Platform for Top‐Gate Devices via Dry Interface Engineering

open access: yesAdvanced Materials, EarlyView.
We reveal the electronic origin of hidden interfacial doping in monolayer MoS2 grown by MOCVD, identifying sulfate related and water like species as intrinsic donors. Through dry interface engineering approach, we demonstrate MOCVD‐grown single‐crystal MoS2 wafers as a transfer‐free platform for the reliable evaluation of intrinsic gate stacks and ...

Stabilized Bi(III) Sites Direct *NH2OH Pathway for Efficient Cyclohexanone Oxime Electrosynthesis

open access: yesAdvanced Materials, EarlyView.
The electron‐buffering effect stabilizes Bi3+ sites under electroreductive conditions, preserving a favorable interfacial water configuration that sustains the selective *NH2OH pathway and enables efficient cyclohexanone oxime electrosynthesis. ABSTRACT Coupling electrocatalytic nitrite reduction reaction (NO2−RR) with cyclohexanone conversion enables ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
