Convective flow reversal in self-powered enzyme micropumps
Ortiz-Rivera, Isamar; Shum, Henry; Agrawal, Arjun; Sen, Ayusman; Balazs, Anna C. (Proceedings of the National Academy of Sciences, 2016-02-22)Surface-bound enzymes can act as pumps that drive large-scale fluid flows in the presence of their substrates or promoters. Thus, enzymatic catalysis can be harnessed for "on demand" pumping in nano-and microfluidic devices ... -
Harnessing catalytic pumps for directional delivery of microparticles in microchambers
Das, Sambeeta; Shklyaev, Oleg E.; Altemose, Alicia; Shum, Henry; Ortiz-Rivera, Isamar; Valdez, Lyanne; Mallouk, Thomas E.; Balazs, Anna C.; Sen, Ayusman (Springer Nature, 2017-02-17)The directed transport of microparticles in microfluidic devices is vital for efficient bioassays and fabrication of complex microstructures. There remains, however, a need for methods to propel and steer microscopic cargo ...
