A Universal Biomolecular Concentrator To Enhance Biomolecular Surface Binding Based on Acoustic NEMS Resonator
In designing bioassay systems for
low-abundance biomolecule detection,
most research focuses on improving transduction mechanisms while ignoring
the intrinsically fundamental limitations in solution: mass transfer
and binding affinity. We demonstrate enhanced biomolecular surface
binding using an acoustic nano-electromechanical system (NEMS) resonator,
as an on-chip biomolecular concentrator which breaks both mass transfer
and binding affinity limitations. As a result, a concentration factor
of 10<sup>5</sup> has been obtained for various biomolecules. The
resultantly enhanced surface binding between probes on the absorption
surface and analytes in solution enables us to lower the limit of
detection for representative proteins. We also integrated the biomolecular
concentrator into an optoelectronic bioassay platform to demonstrate
delivery of proteins from buffer/serum to the absorption surface.
Since the manufacture of the resonator is CMOS-compatible, we expect
it to be readily applied to further analysis of biomolecular interactions
in molecular diagnostics

Hierarchically Mesostructured Aluminum Current Collector for Enhancing the Performance of Supercapacitors
Aluminum (Al) current
collector is one of the most important components
of supercapacitors, and its performance has vital effects on the electrochemical
performance and cyclic stability of supercapacitors. In the present
work, a scalable and low-cost, yet highly efficient, picosecond laser
processing method of Al current collectors was developed to improve
the overall performance of supercapacitors. The laser treatment resulted
in hierarchical micro–nanostructures on the surface of the
commercial Al foil and reduced the surface oxygen content of the foil.
The electrochemical performance of the Al foil with the micro–nanosurface
structures was examined in the symmetrical activated carbon-based
coin supercapacitors with an organic electrolyte. The results suggest
that the laser-treated Al foil (laser-Al) increased the capacitance
density of supercapacitors up to 110.1 F g<sup>–1</sup> and
promoted the rate capability due to its low contact resistance with
the carbonaceous electrode and high electrical conductivity derived
from its larger specific surface areas and deoxidized surface. In
addition, the capacitor with the laser-Al current collector exhibited
high cyclic stability with 91.5% capacitance retention after 10 000
cycles, 21.3% higher than that with pristine-Al current collector
due to its stronger bonding with the carbonaceous electrode that prevented
any delamination during aging. Our work has provided a new strategy
for improving the electrochemical performance of supercapacitors
