3D‐Printed Piezoionic/Bioelectronic Hydrogel for Electro‐Metabolic Regulation of Osteogenic Differentiation

Advanced Healthcare Materials, EarlyView.
A 3D‐printed piezoionic GPMx hydrogel enables stable electromechanical signal generation under mechanical loading, exhibiting long‐term durability and low fatigue. As a bioactive patch, it restores endogenous bioelectricity to stimulate osteogenesis via Ca2+ influx and mitochondrial activation, while simultaneously enabling label‐free alkaline ...

Neutrophil‐Mimetic MRI Enables Ultra‐Early Detection of Vascular Inflammation After Stroke

Advanced Healthcare Materials, EarlyView.
In this study, we developed neutrophil‐mimetic MRI probes that detect ultra‐early neuroinflammation following ischemic stroke by targeting E‐selectin. Within seconds of their injection, these microparticles mimic initial leukocyte adhesion to the activated cerebral endothelium.

Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

Advanced Materials, EarlyView.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–

Infections of the eye.

Singapore medical journal, 1996
Infections of the eye range from the mild to the severe. They may affect the lid, conjunctiva, cornea, lacrimal apparatus, vitreous, orbit or retina. Common presentations, diagnostic methods and treatment are briefly described. The doctor should not only manage outpatients appropriately, but know when to seek the advice of the ophthalmologist when ...

Digital Microneedles for Multiplexed Transdermal Sensing via Fluorescent QR Codes

Advanced Materials, EarlyView.
Digital fluorescent microneedles encode biochemical information in skin into scannable QR codes through threshold‐activated probes that generate binary on/off signals. By transforming analog fluorescence into discrete digital patterns, this platform enables calibration‐free, multiplexed transdermal sensing of physiologically relevant biomarkers ...

A Pressure Microsensor Made of Parylene‐C for Use as Medical Implant

Advanced Materials Technologies, EarlyView.
A monolithic parylene‐C pressure sensor with gold strain gauges provides 6.2 μV$\mu{\rm V}$·mmHg$\cdot{\rm mmHg}$−1$^{-1}$ sensitivity. The morphology of a sputtered thin film strain sensor is granular/columnar, which results in a high gauge factor of 7.5. Thermal bonding and parylene‐C coating create a hermetic cavity.

From Rigid to Soft Robotic Approaches for Neuroendoscopy

Advanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify
