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 ...

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 ...

A Mathematical Model to Analyze the Static Stability of Hybrid (Aero- Hydrodynamically Supported) Vehicles. [PDF]

open access: yes, 2008
Among the new concepts developed for high speed marine vehicles over the last two decades, the "aerodynamic alleviation" approach consists in using an aerodynamic surface to "alleviate" the weight sustained by the hydrodynamic lift.

Oppositely Charged Single Enzyme Nanogels Form Versatile Coacervates for Efficient Enzyme Cascade Catalysis

open access: yesAdvanced Materials, EarlyView.
Oppositely charged single enzyme nanogels (SENs) phase‐separate into bi‐enzymatic coacervate microdroplets, acting as both scaffold and functional units. By tuning SEN ratios, these coacervates create specific microenvironments that enable selective small‐molecule enrichment and efficient intermediate diffusion.

Numerical and Experimental Study of a Bio-Inspired Flapping Wing with Increasing Twist Angle Along the Wingspan

open access: yesMachines
Inspired by the movements of sea turtle forelimbs, this study presents a bio-inspired underwater flapping wing with three degrees of freedom. This flapping wing mechanism can more accurately simulate the rotational motion of a sea turtle’s forelimbs to ...

BioEISense: A Microfluidic Platform for Real‐Time Monitoring of Staphylococcus aureus Biofilm Formation and the Efficacy of Antibiofilm Agents

open access: yesAdvanced Materials Interfaces, EarlyView.
BioEISense is a microfluidic device with integrated impedance sensors, for real‐time, label‐free monitoring of S. aureus biofilms. In this study, the biofilm culture conditions were optimized to support sensitive and reproducible detection of biofilm formation and eradication under dynamic flow‐through conditions. The system was also validated for both

Sensitive and Spatially‐Resolved Electrochemiluminescence via Micropatterning

open access: yesAdvanced Materials Interfaces, EarlyView.
The use of a simple silica nanoparticle surface coating and patterning process can transform ordinary gold electrodes into multiplexed ECL sensing electrodes. Through spatially confined droplet formation and local ECL emission, it is possible to perform multiple analyses simultaneously from individual locations as well as intensify the ECL signal by as
