Transport–Reaction–Signal Coupling in Lateral Flow Assays for Next‐Generation Point‐of‐Care Diagnostics

open access: yesAdvanced Science, EarlyView.
Lateral flow assays are evolving into interdisciplinary, system‐level sensing platforms. Recent innovations are deconstructed through coupled phases of mass transfer, reaction, and signal transduction, revealing interdependence across porous materials, interfacial chemistry, nanolabels, readout devices, and data‐enabled analysis.

H4K12 Lactylation Regulates NDUFS7 to Drive Microglia Reverse Electron Transport in Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
Lactate accumulation after SCI promotes H4K12la lactylation, which upregulates NDUFS7, triggering mitochondrial RET and ROS, enforcing pro‐inflammatory microglial polarization. MM@mPTC, a biomimetic nanotherapeutic, degrades LDHA in activated microglia, reducing H4K12la lactylation and blocking RET, thus curbing ROS, fostering a reparative phenotype ...

Synthesis and electrochemical characterization of thiophenes with pendant fluorescent terpyridine

open access: yes, 2013
A novel series of thiophenes with terpyridine pendant groups were synthesized by Steglich esterification in the presence of DCC/DMAP and the synthesized monomers were electrochemically polymerized onto microelectrodes using glassy carbon and carbon fiber

Metal nanostructure‐coupled label‐free localized surface plasmon resonance biosensors for rapid and sensitive disease diagnosis

open access: yesBMEMat, EarlyView.
LSPR biosensing enables rapid, sensitive, and low‐sample‐volume detection of biomarkers, with broad applications in diagnosing cancer, infectious, and chronic diseases. Advances in nanostructure design, micro/nanofabrication, and microfluidic integration have expanded the potential of LSPR sensors in biomedical diagnostics.

Electrochemical, antibacterial and cytotoxicity investigations of Litchi chinensis mediated Mn3O4 nanoparticles

open access: yesJournal of Taibah University for Science
No studies were reported earlier on Litchi chinensis mediated biosynthesis of Mn3O4 nanoparticles (NPs). We synthesized Mn3O4(aq) and Mn3O4(me) NPs by employing the aqueous and methanolic extracts, respectively of L.

Energy Conservation via Hydrogen Cycling in the Methanogenic Archaeon Methanosarcina barkeri

open access: yesmBio, 2018
Energy conservation via hydrogen cycling, which generates proton motive force by intracellular H2 production coupled to extracellular consumption, has been controversial since it was first proposed in 1981.

Electron compensation‐gated nanomotor for immunomodulation and microenvironment remodeling in bacterial pneumonia therapy

open access: yesBMEMat, EarlyView.
A nanomotor featuring an “electronic lock” via electron compensation in an Au‐Ag alloy ensures therapeutic precision. Near‐infrared light acts as a key, unlocking on‐demand Ag+ release for synergistic bactericidal action and microenvironment remodeling to potently treat bacterial pneumonia. Abstract Bacterial pneumonia treatment is severely hampered by
