Metal-assisted chemical etching in HF/H2O2 produces porous silicon
Xiuling Li,Paul W. Bohn +1 more
TL;DR: In this paper, a simple and effective method is presented for producing light-emitting porous silicon (PSi) using a thin layer of Au, Pt, or Au/Pd is deposited on the (100) Si surface prior to immersion in a solution of HF and H2O2 depending on the type of metal deposited and Si doping type and doping level.
Journal ArticleDOI
Gateable Nanofluidic Interconnects for Multilayered Microfluidic Separation Systems
Tzu Chi Kuo,Donald M. Cannon,Yanning Chen,Joseph J. Tulock,Mark A. Shannon,Jonathan V. Sweedler,Paul W. Bohn +6 more
TL;DR: Externally controllable interconnects, employing nuclear track-etched polycarbonate membranes containing nanometer-diameter capillaries, are described that produce hybrid three-dimensional fluidic architectures that allow complex fluidic and chemical manipulations but requires innovative methods to interface fluidic layers.
Journal ArticleDOI
Nanofluidics in chemical analysis
TL;DR: This critical review begins with a discussion of the fundamental flow physics that distinguishes nanoscale structures from their larger microscale analogs, especially the concentration polarization that develops at nanofluidic/microfluidic interfaces.
Journal ArticleDOI
In-plane control of morphology and tunable photoluminescence in porous silicon produced by metal-assisted electroless chemical etching
TL;DR: In this article, a photoluminescent porous silicon (PSi) was produced by Pt-assisted electroless etching of p−-Si in a 1:2:1 solution of HF, H2O2, and methanol.
Journal ArticleDOI
Manipulating Molecular Transport through Nanoporous Membranes by Control of Electrokinetic Flow: Effect of Surface Charge Density and Debye Length
TL;DR: In this article, the authors investigated molecular transport through nanoporous nuclear track-etched membranes with fluorescent probes by manipulating applied electric field polarity, pore size, membrane surface functionality, pH, and the ionic strength.
