Development of a multiplexed and sensitive biosensing platform is priority for public health security. We report micropore resistance counting based on polystyrene microsphere size-based encoding Clostridium butyricum Argonaute (CbAgo) decoding ultrasensitive detection. Initially, we constructed target DNA-modified coding system counting. Subsequently, the precise recognition cleavage capabilities guide DNA-activated CbAgo protein enable encoded system. Changes in concentration microspheres...
We combined a CRISPR/Cas12a system with hybridization chain reaction (HCR) to develop an ultrasensitive magnetic relaxation switching (MRS) biosensor for detecting viable
Laser-spot-location detection technology based on photodetectors is widely used in the aerospace, medical, military and communication fields. However, most of current research focuses continuous laser visible near-infrared bands, real-time high-precision position a long-wave infrared pulsed lacking. In this paper, spot-position system four-quadrant detector designed for 10.6 μm CO2-driven extreme ultraviolet light source, second-order extended error compensation algorithm Gaussian-spot model...
To investigate the relationship between sports participation and sport trait confidence, 1659 teenagers in primary secondary schools who regularly play football were asked to complete Sports Participation Scale, Collective Self-Esteem Sport Trait Confidence Scale. The results show that (1) positive prediction of on confidence is not significant; (2) collective self-esteem a mediating role confidence; (3) effect occurs through three pathways. study provides theoretical guidance empirical...
CRISPR/Cas12a fluorimetry has been extensively developed in the biosensing arena, on account of its high selectivity, simplicity, and rapidness. However, typical suffers from low sensitivity due to limited trans-cleavage efficiency Cas12a, necessitating integration other preamplification techniques. Herein, we develop an enhanced via a DNAzyme-embedded framework nucleic acid (FNAzyme) substrate, which was designed by embedding four CLICK-17 DNAzymes into rigid tetrahedral scaffold. FNAzyme...
Tunable mid-infrared lasers are widely used in laser spectroscopy, gas sensing and many other related areas. In order to solve heat dissipation problems improve the environmental temperature adaptability of solid-state sources, a tunable all-fiber pumped optical parametric oscillator (OPO) was established, compact thermal control system based on thermoelectric coolers, an automatic circuit, cooling fins, fans pipes integrated designed for laser. This is compact, light air-cooling which...
A theoretical model describing the dynamic process of a continuous-wave Fe2+:ZnSe laser is presented. The influence some operating parameters on output characteristics an studied in detail. results indicate that temperature rise crystal significant with use high power pump laser, especially for doped concentration crystal. optimal length increases decreasing crystal, so simultaneous doping during growth attractive choice, which usually has low and long length. pumping threshold almost stable...
Characteristics of intracavity frequency doubling a diode-pump cesium vapor laser (Cs-DPAL) are studied in detail utilizing the rate equations theory. For Cs-DPAL, very long nonlinear crystals such as LiB3O5 (LBO) and BiB3O6 (BIBO) with relatively small effective coefficient required to get maximum second harmonic (SH) power, periodically poled KTiOPO4 (ppKTP) promising. The reason for this phenomenon is that simulated emission section much higher, although it favorable reduce threshold....
The cross-section is crucial for quantitative characterization and analysis of the absorption process. A model on simultaneous two-photon excitation in Rb-vapor four-wave mixing process established by using coupled-wave equation. Taken into account hyperfine structures 85Rb 87Rb, third-order susceptibility line strength are calculated respectively. Then, influences transition cross section investigated simulation results agree well with experiment results. suggest that high pumping power...
