A Vertically‐Stacked Optoelectronic Sensor for Localized Hemodynamics Monitoring
Advanced Functional Materials, EarlyView.This work introduces a hemodynamics monitoring sensor that features vertically stacked microLEDs and a heterogeneously integrated photodetector. The vertically stacked microLEDs enable localized measurements, and by designing the interoptode distance according to the depth of the target region, this vertically stacked optoelectronic sensor is ...

Advanced Functional Materials, EarlyView.Epitaxial piezoelectric α‐quartz/Si BioNEMS sensors, made using soft chemistry, effectively detect the Chikungunya virus. They have a mass sensitivity of 205 pg Hz−1 in liquid and can detect the virus at a limit of 9 ng mL−1. This development enables high‐frequency mass devices for point‐of‐care testing in healthcare and other electronic applications ...

Engineering Highly Cellularized Living Materials via Mechanical Agitation
Advanced Functional Materials, EarlyView.A mechanical agitation strategy is developed to engineer highly cellularized living materials, achieving cell densities of up to 1 billion cells per milliliter. By precisely tuning properties such as stiffness and toughness in blood clots, the approach is validated in both in vitro and in vivo studies.

, 2014 This presentation of 7 animations demonstrates the Doppler effect, which is used by astronomers to learn about the motions of stars, and to find planets. The principle is simple - in fact, even the animations consist only of expanding circles - but the effect is impressive. http://starguyspeaks.wordpress.com/2014/10/12/on-the-doppler-effect/

Kidney Stone Dissolution By Tetherless, Enzyme‐Loaded, Soft Magnetic Miniature Robots
Advanced Healthcare Materials, EarlyView.Wireless magnetic robots are developed for kidney stone dissolution. The robots navigate through a urinary tract model from bladder and ureter to renal pelvis with the help of external magnetic fields. The filaments are loaded with urease enzyme which catalyzes urea to carbon dioxide and ammonia, thereby increasing pH to basic regime and supporting ...

Advanced Healthcare Materials, EarlyView.A decellularized nerve graft (DNG) is modified to generate a porous DNG (PDNG). The PDNG is used to repair a 30‐mm peripheral nerve injury (PNI) defect, and is compared with isograft, serving as the standard, and DNG, a widely used alternative. The result shows that PDNG facilitated nerve regeneration in long‐gap PNI, evidenced by better‐aligned axonal
