Systems comprising a microfluidic device are provided for maintaining and analyzing tissue slices. Methods for maintaining tissue slices in a microfluidic device are further provided.

Apparatus and methods for in vitro preclinical human trials

A handheld system includes a reference pressure source configured to generate a reference pressure. The handheld system also includes a primary pressure source coupled to the reference pressure source. The primary pressure source is configured to generate a primary pressure in a primary pressure range. The primary pressure is less than the reference pressure, and the primary pressure is induced by the reference pressure source. The handheld system also includes a secondary pressure source coupled to the primary pressure source. The secondary pressure source is configured to generate a secondary pressure in a secondary pressure range. The secondary pressure is less than the primary pressure, and the secondary pressure is induced by the primary pressure source.

Handheld fluid handling systems and methods

The present disclosure outlines a device having a multi-channel potentiostat circuit and a microcontroller for controlling the multi-channel potentiostat circuit. The multi-channel potentiostat circuit includes a counter electrode, a reference electrode, and a first switch between the counter electrode and the reference electrode. The multi-channel potentiostat circuit also includes a plurality of measurement circuits coupled to respective second switches. The microcontroller can configured to provide a first signal to the multi-channel potentiostat circuit to control the first switch, wherein a state of the first switch changes an operating mode of the multi-channel potentiostat circuit. The microcontroller is also configured to provide a second signal to the multi-channel potentiostat circuit to control at least one of the second switches to couple at least one of the plurality of measurement circuits to a working electrode.
