Journal ArticleDOI
Enhancing the performance of paper-based electrochemical impedance spectroscopy nanobiosensors: An experimental approach.
TL;DR: In this article, the performance of paper-based EIS biosensors featuring zinc oxide nanowires (ZnO NWs) directly grown on working electrodes (WEs) was evaluated.
Journal ArticleDOI
Fighting COVID-19: Integrated Micro- and Nanosystems for Viral Infection Diagnostics.
TL;DR: This Perspective reviews the previous and ongoing research efforts on developing integrated micro- and nanosystems for nucleic acid-based virus detection, and highlights promising technologies that could provide better solutions for the diagnosis of COVID-19 and other viral infectious diseases.
Journal ArticleDOI
Fabrication of polydimethylsiloxane (PDMS) nanofluidic chips with controllable channel size and spacing
Ran Peng,Dongqing Li +1 more
TL;DR: Using this method, high quality PDMS nanofluidic chips with a single nanochannel or multiple nanochannels of sub-100 nm width and height and centimeter length can be obtained with high repeatability.
Journal ArticleDOI
Electroosmotic flow in single PDMS nanochannels.
Ran Peng,Dongqing Li +1 more
TL;DR: The electroosmotic flow (EOF) velocity in single PDMS nanochannels with dimensions as small as 20 nm is investigated systematically by the current slope method and the results show that the EOF velocity in smaller nanoch channels with overlapped electric double layers (EDL) is proportional to the applied electric field but is smaller than the ETO velocity in microchannels under the same appliedElectric field.
Journal ArticleDOI
Effects of ionic concentration gradient on electroosmotic flow mixing in a microchannel
Ran Peng,Dongqing Li +1 more
TL;DR: The results show that the electric field and the flow velocity are non-uniform when the concentration dependence of these parameters is taken into consideration, and it is also found that the electrolyte solution essentially cannot enter the channel due to the extremely low electroosmotic flow mobility.
