Ultrasensitive Detection of Porcine Epidemic Diarrhea Virus Infections Using Multivalent DNA Nanostructure‐Enabled Lateral Flow Assay

Advanced Healthcare Materials, EarlyView.
A multivalent DNA nanostructure‐enabled lateral flow assay was developed for rapid, ultrasensitive detection of porcine epidemic diarrhea virus (PEDV) nucleocapsid protein. Designer net‐shaped DNA nanostructures (DNA‐Net) presenting PEDV‐specific aptamers achieved ~1000‐fold enhanced binding, enabling detection of viral copies with Ct ≤ 37.42 within 10

Self‐Assembled Skin Equivalents with Monoclonal CRISPR/Cas9‐Modified N/TERT‐1 Keratinocytes: A Cutting‐Edge model for Human Skin and its Diseases

Advanced Healthcare Materials, EarlyView.
Self‐assembled, scaffold‐free full‐thickness skin equivalents with monoclonal, genetically modified N/TERT‐1 keratinocytes represent a novel in vitro model of human skin and skin diseases. The model is highly robust, reproducible, physiologically relevant, and suitable for high‐throughput applications.

Atomic Layer Deposition Processes: Versatile Platforms for Engineering ZnO‐Chitosan Biointerfaces

Advanced Healthcare Materials, EarlyView.
Vapour phase metalation (VPM), multiplied pulsed vapour phase infiltration (MPI), and O2 plasma‑enhanced atomic layer deposition (PEALD) tailor Zn–chitosan (Zn‑CS) films. PEALD improves wettability and biocompatibility. MPI enhances semiconductor behavior. Antiseptic selectivity: VPM → E. coli; MPI → H. pylori.
