摘要

在许多微流体工作流程中，都需要将试剂添加到液滴中。皮膜注射法可以满足这一需求，但它无法控制每个液滴的注射量。在这里，我们提出了一种改进的皮膜注射方法，它可以向单个液滴注射可控的体积。我们通过调整每个微微注塑事件的注塑持续时间来实现这一目标。这种改进的微微注射方法可用于创建复杂的微流体工作流程，从而控制单个液滴的生化成分。

Manipulating the duration of picoinjection controls the injected volume of individual droplets

The ability to add reagents into droplets is required in many microfluidic workflows. Picoinjection can address this need; however, it is unable to control the injection volume for each individual droplet. Here, we present an improved picoinjection method that can inject controlled volumes into individual droplets. We achieve this by adjusting the injection duration for each picoinjection event. This improved picoinjection method can be used to create complex microfluidic workflows that are able to control the biochemical composition of individual droplets.

期刊介绍： Biomicrofluidics (BMF) is an online-only journal published by AIP Publishing to rapidly disseminate research in fundamental physicochemical mechanisms associated with microfluidic and nanofluidic phenomena. BMF also publishes research in unique microfluidic and nanofluidic techniques for diagnostic, medical, biological, pharmaceutical, environmental, and chemical applications. BMF offers quick publication, multimedia capability, and worldwide circulation among academic, national, and industrial laboratories. With a primary focus on high-quality original research articles, BMF also organizes special sections that help explain and define specific challenges unique to the interdisciplinary field of biomicrofluidics. Microfluidic and nanofluidic actuation (electrokinetics, acoustofluidics, optofluidics, capillary) Liquid Biopsy (microRNA profiling, circulating tumor cell isolation, exosome isolation, circulating tumor DNA quantification) Cell sorting, manipulation, and transfection (di/electrophoresis, magnetic beads, optical traps, electroporation) Molecular Separation and Concentration (isotachophoresis, concentration polarization, di/electrophoresis, magnetic beads, nanoparticles) Cell culture and analysis(single cell assays, stimuli response, stem cell transfection) Genomic and proteomic analysis (rapid gene sequencing, DNA/protein/carbohydrate arrays) Biosensors (immuno-assay, nucleic acid fluorescent assay, colorimetric assay, enzyme amplification, plasmonic and Raman nano-reporter, molecular beacon, FRET, aptamer, nanopore, optical fibers) Biophysical transport and characterization (DNA, single protein, ion channel and membrane dynamics, cell motility and communication mechanisms, electrophysiology, patch clamping).
