Publication number: 20230258636Abstract: A method of manufacturing synthetic particles for use in microfluidic devices is disclosed. The method includes identifying a set of particle characteristics for a fluid-based process. The set of particle characteristics can include a synthetic particle density and one or more of a size, compressibility, elastic modulus, or porosity. The method includes selecting an input material for the synthetic particles based on the set of synthetic particle characteristics. The method may include selecting an additive based on the set of synthetic particle characteristics. The method includes providing input material and the additive into a droplet generator to create one or more synthetic particles having the set of synthetic particle characteristics, and modifying a surface characteristic the synthetic particles, such that the synthetic particles bind to a target particle in a solution.Type: ApplicationFiled: February 10, 2023Publication date: August 17, 2023Applicant: The Charles Stark Draper Laboratory, Inc.Inventors: Ryan Dubay, Jason Fiering, Eric Darling

Publication number: 20230234058Abstract: A microfluidic system can include a substrate comprising an elastic material and defining a microfluidic channel. The substrate can have a first set of dimensions defining a thickness of a wall of the microfluidic channel and a second set of dimensions defining a width of the microfluidic channel. A transducer can be mechanically coupled with the substrate. The transducer can be operated at a predetermined frequency different from a primary thickness resonant frequency of the transducer. A thickness and a width of the transducer can be selected based on the first set of dimensions defining the thickness of the wall of the microfluidic channel and the second set of dimensions defining the width of the microfluidic channel.Type: ApplicationFiled: April 3, 2023Publication date: July 27, 2023Applicant: The Charles Stark Draper Laboratory, Inc.Inventors: Ryan Dubay, Jason Fiering, Rebecca Christianson, Jason Durant, Charles Lissandrello

Publication number: 20230183631Abstract: Transfer of genetic and other materials to cells is conducted in a hands-free, automated and continuous process that includes flowing the cells between electroporation electrodes to facilitate delivery of a payload into the cells, while acoustophoretically focusing the cells. Also described is a control method for the acoustophoretic focusing of cells that includes detecting locations of cells flowing through a channel, such as with an image analytics system, and modulating a drive signal to an acoustic transducer to change the locations of the cells flowing in the channel. Finally, an electroporation driver module is described that uses a digital to analog converter for generating an electroporation waveform and an amplifier for amplifying the electroporation waveform for application to electroporation electrodes.Type: ApplicationFiled: December 19, 2022Publication date: June 15, 2023Applicant: The Charles Stark Draper Laboratory, Inc.Inventors: Vishal Tandon, Charles A.

Publication number: 20190292565Abstract: A system for sequential exposure of particles to different fluid streams includes an acoustic actuator device for acoustically driving one or more substrates and a microchannel device of the one or more substrates that receive particles in a first flowing fluid, moves the particles to a second flowing fluid, then moves the particles out of the second flowing fluid using acoustic radiation generated by the acoustic actuator device. The system can control residence times in the streams. According to one use, the first flowing fluid is a cell buffer and the second flowing media is an electroporation buffer. An electroporation system is placed in or downstream of the acoustic actuator device. However, in other uses, the second flowing media might be a wash buffer.Type: ApplicationFiled: March 20, 2019Publication date: September 26, 2019Inventors: Vishal Tandon, Charles A.
