Nano‐Optical Biomolecular Interaction Sensing Within Complex Media via Peptide Hybrid Ligand Conjugation

Small, EarlyView.
We have designed a new type of nanoparticle‐based optical biosensor whose surface has been engineered with peptide‐polymer hybrids so that sensing of small protein‐protein interactions can be performed in simple buffers and complex biological liquids including animal and human serum. Measurements can be performed simply by mixing nanosensors with media

Accessing Both Electrochemical SEIRA and SERS With Highly Sensitive Metamaterials for Enhanced Molecular Identification

Small, EarlyView.
Surface‐enhanced infrared absorption (SEIRA) and Raman scattering (SERS) are complementary, highly sensitive molecular detection methods. A reusable metamaterial substrate capable of combined SEIRA and SERS is used here for real‐time sensing, tracking interfacial dynamics in an electrochemical reaction and detecting symmetry‐breaking behavior at the ...

High‐Throughput FRET Affinity Screening Technique (HTFAST) for Cell‐Free Expressed Binding Protein Characterization

Small, EarlyView.
High‐Throughput FRET Affinity Screening Technique (HTFAST) for quantitative, purification‐free affinity screening of cell‐free expressed binders. A fluorescent‐protein‐fused binder (donor) is expressed directly in crude E. coli cell‐free lysate and titrated against a dye‐labeled antigen (acceptor).

Titanium Oxide Thin Films With Metal Nanodisks as Plasmonic Metamaterial Photocatalyst Sheets for IPA‐Assisted CO2 Reduction

Small, EarlyView.
Plasmonic metal nanodisks (Ag, Au, Pt, Pd) combined with TiO2 thin films were fabricated into periodic metamaterial photocatalyst sheets by using standard semiconductor methods. Under visible light, Pt/TiO2 and Pd/TiO2 achieved hydrogen and methane production from CO2 and water using isopropyl alcohol, demonstrating promising solar‐fuel production ...

Design, synthesis and activity evaluation of tetrahydroisoquinoline‐based programmed cell death ligand 1 inhibitors

Smart Molecules, EarlyView.
Based on a 3D‐quantitative structure‐activity relationship pharmacophore model, structural optimization of Y6 yielded Y7f. Mechanistic studies revealed that Y7f acted as a programmed death receptor 1/programmed cell death ligand 1 (PD‐L1) interaction inhibitor by inducing PD‐L1 dimerization. Y7f restored T‐cell function.
