Aspects of the present disclosure include methods of producing a cellular suspension from a tissue sample by applying resonant acoustic energy to a container comprising the tissue sample in a manner sufficient to produce a cellular suspension from the tissue sample. Resonant acoustic mixers and kits for use in producing a cellular suspension from a tissue sample are also provided.

Devices, systems, and their methods of use, for generating droplets are provided. One or more geometric parameters of a microfluidic channel can be selected to generate droplets of a desired and predictable droplet size.

Systems, devices, and methods for kinetic release testing of compounds are discussed herein. Ultrasonic agitation, with resultant cavitation and acoustic streaming, is used to breakdown and release drugs from one or more compounds to form a solution. The system uses small volumes of solvent to increase accessibility and portability of the system. Once dissolved, the solution is passed to a sampling system for calculating kinetic release behavior. The kinetic release behavior can be compared to existing reference data to identify the compound and/or confirm accurate manufacture by comparison of dissolution characteristics of the active ingredients. In some embodiments, streak photography and hydrophone measurements are used to study the effects of system parameters on the acousto-hydrodynamic environment.

The microbubble generator includes: an air dissolving tank, having an air dissolving cavity defined therein, and an inlet and an outlet configured to allow water to flow in and out, the inlet being located above the outlet; a baffle, provided in the air dissolving tank, at least partially located between the inlet and the outlet in a horizontal direction, and provided with a gap and/or a through hole; and a cavitator, provided outside the air dissolving tank and connected with the outlet, or provided at the outlet.

A bioFET device includes a semiconductor substrate having a first surface and an opposite, parallel second surface and a plurality of bioFET sensors on the semiconductor substrate. Each of the bioFET sensors includes a gate formed on the first surface of the semiconductor substrate and a channel region formed within the semiconductor substrate beneath the gate and between source/drain (S/D) regions in the semiconductor substrate.

The present disclosure relates to a method for storage or transportation of graphene oxide. The method for storage or transportation of graphene oxide comprises the steps of: carrying out wet spinning of a graphene oxide spinning solution to a coagulating bath to obtain graphene oxide pellets; drying the obtained graphene oxide pellets; storing or transporting the dried graphene oxide pellets; and redispersing the stored or transported graphene oxide pellets.

Disclosed is an apparatus and method for providing asymmetric oscillations to a container. The container may include a fluid, a particle, and/or a gas. A vibration driver attached to the container provides asymmetric oscillations. A controller connected to the vibration driver controls an amplitude, frequency, and shape of the asymmetric oscillations. An amplifier amplifies the asymmetric oscillations in response to the controller. A sensor disposed on the vibration driver provides feedback to the controller.
