Label Free Detection of Programmed Death Ligand 1 Protein Biomarker by Quartz Tuning Fork-Based Biosensor

Journal of the Electrochemical Society, 2023
Programmed death ligand 1 (PD-L1) is expressed on the membrane of many types of breast cancer cells and it helps the cancerous cells to escape the surveillance of the immune system.

Direct Ink Writing 3D Printing of Recyclable and Thermally Stable Vitrimers

Advanced Materials Technologies, EarlyView.
Vitrimers hold great promise in additive manufacturing as defect‐insensitive, repairable, and recyclable feedstocks. A thin‐film additively manufactured process is developed for a high‐performance vitrimer that is difficult to process traditionally.

Millisecond‐Switching Dual‐Band/Dual‐Polarization Ka‐Band Wavefront Control Enabled by a Complementary Liquid‐Crystal Metasurface

Advanced Materials Technologies, EarlyView.
An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype

TADF‐Emitting Dendrimers for Scalable Bar‐Coating Fabrication of Light‐Emitting Electrochemical Cells

Advanced Materials Technologies, EarlyView.
TADF‐emitting dendrimers promise to enable scalable solution‐based fabrication of efficient electroluminescent devices by the virtue of an attractive set of properties. Here, we report on how light‐emitting electrochemical cells, comprising the TADF‐dendrimer tBuCz2m2pTRZ, can be fabricated by scalable bar‐coating under ambient air and deliver uniform ...

Modulating Integrin and Growth Factor Signaling With Peptides: Strategies to Synergistically Enhance Bone Tissue Regeneration

Advanced Science, EarlyView.
It has been demonstrated that, in the bone extracellular matrix (ECM), integrins and growth factor receptors (GFRs) engage in synergistic signaling to guide bone healing and regeneration. This review provides a comprehensive overview of current strategies using ECM‐derived peptides to recreate the cellular microenvironment and harness synergistic ...

AI‐Based D‐Amino Acid Substitution for Optimizing Antimicrobial Peptides to Treat Multidrug‐Resistant Bacterial Infection

Advanced Science, EarlyView.
This study constructed the first D‐amino acid antimicrobial peptide dataset and developed an AI model for efficient screening of substitution sites, with 80% of candidate peptides showing enhanced activity. The lead peptide dR2‐1 demonstrated potent antimicrobial activity in vitro and in vivo, high stability, and low toxicity.
