Microfabricated polyacrylamide devices for the controlled
The ability to spatially confine living cells or small organisms while dynamically controlling their aqueous environment is important for a host of microscopy applications. Here, we show how polyacrylamide layers can be patterned to construct simple microfluidic devices for this purpose. We find that polyacrylamide gels can be molded like PDMS into micron-scale structures that […]

Microfabricated Drug Delivery Devices: Design, Fabrication
In addition, the current status and future prospects of different types of microfabricated devices for controlled drug delivery are summarized and analyzed with an emphasis on various routes of administration including ocular, oral, transdermal, and implantable systems.
Two fundamental approaches for the coupling of microfabricated devices to electrospray mass spectrometry (ESI-MS) have been developed and evaluated. The microdevices, designed for electrophoretic separation, were constructed from glass by standard photolithographic/wet chemical etching techniques. Both approaches integrated sample inlet ports, preconcentration sample loops, the separation

Nucleic acids are the fundamental building blocks of life and are found in all living things. In recent years, their functions have been shown to extend beyond the Watson-Crick base pair recognition of complementary strands. Molecules (known as aptamers) consisting of 40-50 nucleotides have...
US Patent for Flow control in microfluidic systems Patent
Microfluidic systems and methods including those that provide control of fluid flow are provided. Such systems and methods can be used, for example, to control pressure-driven flow based on the influence of channel geometry and the viscosity of one or more fluids inside the system. One method includes flowing a plug of a low viscosity fluid and a plug of a high viscosity fluid in a channel

An innovative microfluidic system comprising a 25 µL chamber to hold devices in a flow path was designed by Groothuis and Verpoort to provide perifusion and simultaneously improve detection of short-lived metabolic intermediates [3,64,142–144], exploiting the single-pass perfusion capability and high cell to medium ratio in microfluidic
- Who are Rezaul K Chowdhury and Walid El-Shorbagy?
- Rezaul K. Chowdhury and Walid El-Shorbagy are authors and work in the Department of Civil and Environmental Engineering at United Arab Emirates University, Al Ain, United Arab Emirates.
- How is water treated at Hvidovre Waterworks?
- At Hvidovre Waterworks, water undergoes a simple treatment that includes aeration on cascade trays and two step serial sand filtration. The carbon filtration unit is installed at the outlet of the sand filter before the water is pumped to the drinking water tank. This setup is similar to the one at Frederiksberg waterworks.
- How is water in Sjaelsoe treated?
- Water in Sjaelsoe undergoes a treatment process that includes sand filtration, flocculation, sedimentation, ozone treatment, and a final scrubbing with biological active carbon filtration. Due to the use of fertilizers, many of the inland waters in Denmark, including Sjaelsoe, have suffered from eutrophication.
- How was ground water treated in the Valpovo region?
- The ground water from the Valpovo region was previously treated by aeration and sand filtration for the removal of iron, manganese, ammonium and other present pollutants. The physical and chemical parameters of the ground water and ammonium concentration were determined in the ground water after the pre-treatment.
