The lateral flow immunoassay test (LFT), as a method of point care test, is widely used in disease diagnosis, food security, and environment observation due to its portability testing rapidity. A fluorescence was developed recently enhance the sensitivity accuracy LFT. However, for most reporters, their emission excitation wavelengths are located ultraviolet or visible region. Serum whole blood significantly absorbs scatters light this region, will result background signal interference. In...

We report a new extended coupled Lorentz oscillator (ECLO) model by adding phase factor for the first time, to best of our knowledge, in contrast conventional (CLO) describing analogue electromagnetically induced transparency (EIT) dimer, which is composed two identically broken eccentric silver nanorings (ESNRs) arranged an asymmetric manner. Based on finite element method, distribution features absorption spectra, charges, and electric field ESNRs are numerically simulated under action...

The localized surface plasmon resonance can be generated on the of nano-metamaterial by interaction between and light field, also many oscillation modes occur in process hybridization infinitesimal composite structures, which is widely used for adjusting resonant frequency optical domain. Recently, analogue electromagnetically induced transparency（EIT) has been realized low-loss nano-metamaterial, well known as transparency（PIT). In atomic physics, EIT an effect originates from destructive...

We report on an experimental observation of constructive quantum interference between two atomic transition pathways 3P1/2-5S (or 4D) and 3P3/2-5S via equal-frequency hybrid excitation collision-aided radiative in Na2-Na system. Through the special processes, is realized for a Λ-type quantum-beat configuration with widely-spaced doublet (about 17 cm-1) excited sodium atom driven by one laser. The dependences argon buffer gas pressure sample temperature are also examined.

We propose a coupling model to describe the interaction between bright and dark modes of plasmons dimer composed two orthogonal gold nano-rods (GNRs), referred as BDMC model. This shows that eigen-frequencies coupled are governed by Coulomb potential electrostatic potential. With model, behaviors coefficient frequency offset, which is new parameter introduced here, revealed. Meanwhile, asymmetric behavior related gap GNRs explained. Using harmonic oscillator parameters obtained mode...

In this study, nanoporous gold (NPG) was deposited on a screen-printed carbon electrode (SPCE) by the dynamic hydrogen bubble template (DHBT) method to prepare an electrochemical sensor for simultaneous determination of Pb2+ and Cu2+ square wave anodic stripping voltammetry (SWASV). The electrodeposition potential time NPG/SPCE preparation were investigated thoroughly. Scanning electron microscopy (SEM) energy-dispersive X-ray diffraction (EDX) analysis confirmed successful fabrication...

Based on the counter-diabatic protocol in quantum physics and quasi-phase-matching method nonlinear optics, we present a of achieving robust energy transfer between sum frequency signal fields an optical crystal system by adding field (CDF). Adding CDF does not loosen adiabatic condition, but rather separates single original diabatic step into two so that remains adiabatic. The resulting steps exhibit tunneling, where second is inverse first one. Moreover, predict fabrication with...

This paper reports a new lithography method using thin-film edge electrodes (TEEs) to collectively transfer nanopatterns by generating oxide on the substrate surface via an electrochemical reaction (ECR). Nanometric thick TEEs are formed sidewall of insulating stamping structures. ECR-based patterns have same width and shape as because ECR is induced only between conductor substrate. Oxide 300 nm 70 in were transferred Si millimeter-scale area.

Bloodstream infection is a major health problem worldwide, with extremely high mortality. Detecting in the early stage challenging due to low concentration of bacteria blood. Digital PCR provides unparalleled sensitivity and can achieve absolute quantification, but it time-consuming. Moreover, presence unavoidable background signals negative controls poses significant challenge for single-molecule detection.
