  • Publication number: 20240042425
    Abstract: Provided is a method of generating droplets that includes aspirating a first liquid into a tube, positioning the tube over a receiving liquid, and ejecting the first liquid to generate a plurality of droplets that contact the receiving liquid and remain discrete even after contacting the receiving liquid. Whereas many other droplet generators require complex microfluidics, the present methods allow generation of droplets without the need for microfluidics. The methods can be performed with existing commercially available macro-fluidic liquid handling devices. The methods can be used for digital PCR, digital MDA, enzyme screening, single cell analysis, and other applications involving droplets.

  • Publication number: 20230313321
    Abstract: The present disclosure provides materials and methods for detecting the presence of a target, such as a nucleic acid, biomolecule or biological particle, or virus genome in a sample. The present disclosure further provides point of care detection methods that cane done quickly and simply, optionally without sophisticated instrumentation. The present disclosure further provides improved methods for detecting and quantifying detection signals from various emulsions.

  • Publication number: 20230212646
    Abstract: Provided is a method including encapsulating a biological material in a droplet having a volume of 500 nl or less, depositing the droplet to an addressable location of a substrate, and performing mass spectroscopy on the droplet. The method can further include conducting omic analysis on the droplet, such as sequencing DNA or analyzing mRNA, after the mass spectroscopy. In some cases, the method can be used to screen thousands of genetically different cells to identify correlations between genetics and the production of a metabolite, wherein the metabolite is detected by mass spectroscopy. Also provided is a system for performing the method.

  • Publication number: 20200261879
    Abstract: The methods described herein, referred to as particle-templated emulsification (PTE), provide an improved approach for generating a monodisperse emulsion that encapsulates target particles of interest without requiring the use of a microfluidic device. Monodisperse droplets may be effectively obtained by using monodisperse particles to template the formation of droplets, which can include, e.g., monodisperse single-emulsion droplets, multiple-emulsion droplets, or Giant Unilamellar Vesicles (GUV), without destroying the integrity of the droplets.
