In an electronic integrated circuit, all of the necessary components are fabricated onto a single semiconductor, which eliminates the need for manual assembly of the individual transistors, capacitors, and resistors. Thorsen et al. (p. 580; see the cover) have now fabricated an analog in a microfluidics system with a set of individually addressable microvalves. Such a system can act as a fluidi...

We introduce an integrated microfluidic device consisting of a biomolecule concentrator and a microdroplet generator, which enhances the limited sensitivity of low-abundance enzyme assays by concentrating biomolecules before encapsulating them into droplet microreactors. We used this platform to detect ultralow levels of matrix metalloproteinases (MMPs) from diluted cellular supernatant and sho...

Inspired by the principles of biological evolution, biologists--and others--have in recent decades harnessed the power of "natural" selection to sift through huge libraries of genes and find those with desirable properties. At the same time, the demand for high-throughput biochemical and genetic assays and screens has driven the development of increasingly miniaturised assay systems. An excitin...

METHODS: The quantitative methodology was based on ELISA in poly(dimethylsiloxane)-gold nanoparticle composite microreactors. CdTe and ZnSe quantum dots were bioconjugated with antibodies for sandwich immunoassay. After the CdTe and ZnSe quantum dots were dissolved, Cd and Zn were detected by square-wave anodic stripping voltammetry to enable the quantification of the two biomarkers. The two bi...

We introduce a new strategy for fabricating a seamless three-dimensional (3D) helical microreactor utilizing a silicone tube and a paraffin mold. With this method, various shapes and sizes of 3D helical microreactors were fabricated, and a complicated and laborious photolithographic process, or 3D printing, was eliminated. With dramatically enhanced portability at a significantly reduced fabric...
