Metal-assisted chemical etching in HF/H2O2 produces porous silicon

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

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.
