Lithography‐Free Site‐Specific Synthesis of Size‐Tailored Platinum Dichalcogenides

Advanced Materials Technologies, EarlyView.
This study proposes a streamlined strategy for synthesizing site‐specific, size‐tunable Pt dichalcogenides by pre‐defining Pt templates via focused ion beam (FIB). Utilizing only FIB and thermal treatment, this approach reduces processing steps and avoids issues like carbon contamination and edge defects from lithographic etching.

A Degradable Device for Sustainable Capillary Blood Sampling

Advanced Materials Technologies, EarlyView.
The device features a compostable 3D‐printed storage compartment for liquid blood collection and a degradable, poly(ɛ‐caprolactone)‐coated magnesium microneedle patch hidden within a suction cup. Manual compression deploys the MNs, creating small skin punctures, and the subsequent release of compression generates the negative pressure required for ...

Plasmonic Metasurfaces with Structural Chirality and Pseudo‐Chirality for Enhanced Circular Dichroism and Enantiomeric Recognition

Advanced Optical Materials, EarlyView.
A planar plasmonic metasurface composed of asymmetric gold nanostructures is shown to exhibit both anisotropic and chiral/pseudo‐chiral optical responses. By tailoring the polarization and angle of incidence, the metasurface significantly enhances optical chirality and enables enantiospecific detection.
