Lead-free perovskite/HfSe2 surface plasmon resonance biosensor design via multi-metric optimization, Monte Carlo robustness analysis, and machine learning

Replacing toxic lead in perovskite-enhanced surface plasmon resonance (SPR) biosensors is critical for environmentally sustainable sensing, yet the performance of lead-free alternatives in multilayer architectures remains poorly characterized. We…

Near-Field Coupling in Plasmonic Nanoarrays: Tailoring Radiative and Non-Radiative Losses Through Gap Engineering

We demonstrate, through finite-difference time-domain (FDTD) simulations, that near-field coupling in ordered 2D nanoarrays of gold nanoparticles can mitigate thermal losses. By comparing the electric field intensities inside the gold nanorods with…

Principles of NMDA receptor co-agonism at cortical fast-spiking GABAergic interneurons in the adolescent prefrontal cortex

Abstract N-methyl-D-aspartate receptors (NMDARs) populate fast-spiking (FS)-parvalbumin-positive (PV + ) GABAergic interneurons (INs), where they play a critical role in shaping circuit motifs and memory. However, it is largely unknown whether and…

Optical Properties of Single CsPbBr3 Perovskite Quantum Dots Synthesized by a Modified Ligand-Assisted Reprecipitation Method

Colloidal perovskite quantum dots (pQDs) are promising quantum light emitters, yet single-pQD studies have so far relied mostly on hot-injection synthesis, which requires precise temperature control and an inert atmosphere. Demonstrating high…
