The biological activities of nanoparticles (NPs), which include endocytosis by macrophages and subsequent intracellular degradation and/or release, transfer to other cells, or translocation across tissue barriers, highly depend on their fate in living organisms. Yet, especially the distal "barrier-crossing" trafficking NPs, is still unclear. exosome (Exo) plays a crucial role intercellular communication barrier trafficking. Here, we report that ZnCdSe@ZnS quantum dots (QDs), as...
The polymerase chain reaction (PCR) has unique advantages of sensitivity, specificity and rapidity in pathogen detection, which makes it at the forefront academia application molecular biology diagnosis.
A simple method for microfluidic paper-based sample concentration using ion polarization (ICP) with smartphone detection is developed. The concise and low-cost ICP analytical device, which consists of a black backing layer, nitrocellulose membrane, two absorbent pads, fabricated the lamination widely used lateral flow strips. Sample on membrane monitored in real time by whose camera to collect fluorescence images from device. custom image processing algorithm running track concentrated...
Abstract The most commonly used curing agents for soy‐based adhesives are polyamines, which have the problem of low solid content and/or high viscosity. To overcome this problem, a new type polyamidoamine (PADA) resin was synthesized and applied to soy flour‐based improve their water resistance. PADA solution obtained had 50 wt% viscosity 270 cP. optimum weight ratio flour/PADA/maleic anhydride prepare adhesive 40/7/1.68. wet strength plywood prepared at 0.82 MPa, meant could be as II...
Real-time polymerase chain reaction (PCR) is the standard for nucleic acid detection and plays an important role in many fields. A new chip design proposed this study to avoid use of expensive instruments hydrophobic treatment surface, a injection method solves issue bubbles formed during temperature cycle. We built battery-powered real-time PCR device follow using fluorescence developed independently designed electromechanical control system analysis software cycle, photoelectric coupling,...
Almost all the reported capillary convective polymerase chain reaction (CCPCR) systems to date are still limited research use stemming from unresolved issues related repeatability, reliability, convenience, and sensitivity. To move CCPCR technology forward toward commercialization, a couple of critical strategies innovations discussed here. First, single- dual-end heating analyzed compared between each other. Especially, different solutions for proposed discussed, heat transfer fluid flow...
We reported a rapid, convenient, and easy-to-use genotyping method for hepatitis B virus (HBV) based on the smartphone at point-of-care (POC) settings. To perform HBV especially genotypes A, B, C, D, is used to image analyze one-step immunoassay lateral flow strip functionalized with genotype-specific monoclonal antibodies (mAbs) multiple capture lines. A light-emitting diode (LED) positioned top of shine lines excitation. Fluorescence detection obtained whose camera take fluorescent images....
Temperature control is the most important and fundamental part of a polymerase chain reaction (PCR). To date, there have been several methods to realize periodic heating cooling thermal-cycler system for continuous-flow PCR reactions, three them were widely used: thermo-cycled thermoelectric cooler (TEC), block, thermostatic heater. In present study, new approach called open-loop controlled single TEC was introduced thermal cycle during amplification process. Differing from former methods,...
Abstract High efficient and stable droplets preparation is an essential technology in digital PCR (dPCR) other analytical fields. In this paper, a microfluidic device called vertical step emulsification (VSE) to produce emulsion rapidly off‐chip developed. VSE prepares by perfluoroalkoxy (PFA) capillary microcentrifuge tube, when the continuous water phase PFA jets into static oil tube at certain speed, emulsified due sudden change of surface tension. order control droplet size accurately,...
The self-activated micropump capable of velocity-stable transport for both single-phased plug and double-phased droplet through long flow distance inside 3D microchannel is one dream microfluidic scientists. While several types passive micropumps have been developed based on different actuation mechanisms, until today, it still bottleneck to realize such a satisfied the stable delivery single liquid (e.g., meters), due lack innovative mechanism in previous methods. To solve this problem,...
