Abstract Nowadays droplet microfluidics is widely used to perform high throughput assays and for the synthesis of micro- nanoparticles. These applications usually require packaging several reagents into droplets their mixing start a biochemical reaction. For rapid microfluidic devices additional functional elements that make designs more complex. Here we series 2D numerical simulations, followed by experimental studies, introduce novel asymmetric flow-focusing generator, which enhances...
Chemically synthesized inorganic lead halide perovskite lasers based on nanostructures, generating coherent light at room temperature, and having a low threshold, have become powerful tools for various photonic applications. However, to fabricate high-quality nanostructures substrate, it is crucial provide certain surface parameters precisely keep synthesis conditions. Here, we report novel approach the one-step fabrication of CsPbBr3 nanolasers in form suspension obtained by rapid...
Droplet microfluidics is an extremely useful and powerful tool for industrial, environmental, biotechnological applications, due to advantages such as the small volume of reagents required, ultrahigh-throughput, precise control, independent manipulations each droplet. For generation monodisperse water-in-oil droplets, usually T-junction flow-focusing microfluidic devices connected syringe pumps or pressure controllers are used. Here, we investigated droplet-generation regimes in a device...
Solid-state nanopore devices with plasmonic nanoantennas are powerful tools that allow for working individual particles and molecules in solution as well providing light-induced control of ionic current flow through them. However, the manipulation by light still requires high power densities and, thus, results optical heating nanopore. Here, we solve this problem using a 5 nm gap bow-tie nanoantenna on SiNx membrane irradiated broadband spectrum incident light. In regime, photons not only...
The aim of this work was to determine a design microfluidic droplet generator which provides the best mixing two components within during its formation. Simulation droplets' formation in various designs generators performed. Dependences index from capillary number and viscosity continuous phase were obtained for each design. determined directly after droplet. It found that small numbers correspond lower due increase droplets diameter. high vortex flows area leads an asymmetric designs, but...
Microfluidics is a rapidly growing area that provides innovations in biotechnology, medical diagnostics, and life science. Along with the commercial solutions, there are open-source projects aimed to make such technologies more affordable flexible for end users. In this article, we developed an open-source, low-cost, easy-to-use microfluidic pressure controller modular design based on electropneumatic regulators introduce liquids into devices under constant pressures. For implementation of...
