  • Tubing-free, sample-to-droplet microfluidic system and chip
    Patent number: 11998912
    Abstract: A tubing-free, sample-to-droplet microfluidic system includes a tubing-free, sample-to-droplet microfluidic chip; a valve control system connected to the tubing-free, sample-to-droplet microfluidic chip; a vacuum system fluidly connected to the tubing-free, sample-to-droplet microfluidic chip; and a droplet formation pressure system fluidly connected to the tubing-free, sample-to-droplet microfluidic chip. A microfluidic chip for a tubing-free, sample-to-droplet microfluidic system includes a tubing-free, sample-to-droplet interface section; a droplet mixing section in fluid connection with the tubing-free, sample-to-droplet interface section to received droplets therefrom; an incubation section in fluid connection with the droplet mixing section to receive droplets therefrom; and a detection section in fluid connection with the incubation section to receive droplets therefrom.
