Abstract: Provided herein are microfluidic devices that can be configured to generate an electrophoretic flow that is in opposition to a fluid flow through a microcapillary of a microfluidic device provided herein for nucleic acid isolation. Also provided herein are systems comprising such. Also provided herein are methods that include adding an amount of a sample comprising nucleic acids to the inlet area of a microfluidic device as provided herein, generating a first fluid flow through a microcapillary of a microfluidic device provided herein; and applying a uniform electric field to the microfluidic device, where the uniform electric field generates an electrophoretic flow that is in opposition to the fluid flow. Methods as described herein can further comprise quantifying or otherwise characterizing isolated nucleic acids separated by devices, systems, and methods as described herein.

Abstract: A glove includes a glove body including opposing dorsal and palmar side panels, opposing proximal and distal ends, a wrist portion formed in the proximal end, and finger stalls formed in the distal end. An elongate strap has an inner end secured to the wrist portion of the glove body and an opposed free outer end, and a plurality of weight-receiving pockets formed in the elongate strap between the inner end of the elongate strap and the outer end of the elongate strap. Corresponding engagement and complemental engagement elements are carried by the elongate strap. The elongate strap is movable between a first position extending away from the wrist portion and a second position wrapped about the wrist portion engaging the engagement element to the complemental engagement element securing the elongate strap in the second position.
