Protein‐Nanoarchitectures for Low‐Field Intracellular Electro‐Immunomodulation

Advanced Functional Materials, EarlyView.
DHQ‐SDH‐mediated binding of AuNPs drives the formation of interconnected, chain‐like nanoarchitectures with enhanced electrical conductivity. These conductive assemblies undergo macrophage uptake and enable low‐field electrical stimulation, promoting M1‐to‐M2 phenotypic switching with decreased iNOS and increased CD206 expression. Such protein‐mediated

Co(II), Ni(II), Cu(II), and Zn(II) complexes derived from 4-[{3-(4-bromophenyl)-1-phenyl-1H-pyrazol-4-ylmethylene}-amino]-3-mercapto-6-methyl-5-oxo-1,2,4-triazine

Beni-Suef University Journal of Basic and Applied Sciences, 2016
A new series of Co(II), Ni(II), Cu(II) and Zn(II) complexes were prepared with bidentate ligand derived by condensation of 4-amino-3-mercapto-6-methyl-5-oxo-1,2,4-triazine with 3-(p-bromophenyl)-1-phenyl-1H-pyrazolecarboxaldehyde. The Schiff base and its

Surface plasmon-coupled emission for applications in biomedical diagnostics [PDF]

, 2009
Surface plasmon-coupled emission (SPCE) is a phenomenon whereby the light emitted from a fluorescent molecule can couple into the surface plasmon of an adjacent metal layer resulting in highly directional emission in the region of the surface plasmon ...

Raman Chemical Imaging of Chromate Reduction Sites in a Single Bacterium Using Intracellularly Grown Gold Nanoislands [PDF]

, 2011
Imaging live molecular events within micro-organisms at single-cell resolution would deliver valuable mechanistic information much needed in understanding key biological processes. We present a surface-enhanced Raman (SERS) chemical imaging strategy as a

Nano Borophene as a Programmable 2D Scaffold for Organized DNA Assembly and Long‐Range Energy Transfer

Advanced Functional Materials, EarlyView.
Borophene is introduced as a programmable 2D bio‐interface that organizes DNA through dual boron–sulfur and nucleobase interactions. This molecular architecture enables efficient long‐range nanosurface energy transfer, establishing new design principles for functional nano–bio interfaces and amplification‐free optical biosensing.
