Microfluidics enables nanoparticle
synthesis
Dolomite has been working with Newcastle University as part of a project to explore the application of microfluidics for the synthesis of nanoparticles for use in biochemistry
Microfluidics, often called lab-on-a-chip, is an exciting new field of science and engineering that enables very small-scale fluid control and analysis, allowing instrument manufacturers to develop smaller, more cost-effective and more powerful systems With lab-on-a-chip technology, entire complex chemical management and analysis systems are created in a microfluidic chip and interfaced with, for example, electronic and optical detection systems

Microfluidics 'to revolutionise DNA analysis'
UK microfluidic expert Dolomite has been working on several projects relating to the use of microfluidic devices for the analysis of DNA, for such purposes as forensics and disease diagnosis
For this project Dolomite created a custom glass microchip with multiple reaction chambers.
This was manufactured undertaking processes such as lithographic patterning, isotropic etching of glass substrates and the accurate thermal bonding of glass substrates.
"The manufacture of this type of device is a very complex process," said Gillian Davis, commercial director at Dolomite.

"However, microfluidics offers high efficiency, versatility, speed, and economy of analysis.
"This technology also has a very low consumption of reagents and analytes, so it brings both cost and environmental benefits to bioscience and drug discovery projects.
"Furthermore, its greatest advantage is the ability to perform parallel-array or multidimensional types of analyses in a small localised environment".
The nanoparticle synthesis project at Newcastle University is headed by Mike Loughran, team leader microfluidics and sensor technologies, at the school of chemical engineering and advanced materials.
Working with Dolomite and Andrea Beck from HAS Budapest, Mike Loughran has been exploring, how in the future, scientists will be able to control specific chemical reactions in a localised microchip environment, enabling different nanoparticles to be designed for a specific purpose e.g the synthesis of silicon based fluorescent nanoparticles (quantum dots) to label biomolecules for diagnostic assays, polymeric nanosensors for intracellular analysis and drug delivery, and catalytic nanoparticles for specific chemistries or for purification by adsorbing pollutants.
"I am very happy with the professionalism and attention to detail that I have received from Dolomite," said Loughran.
"In particular I am very impressed with the speed of the processing, alignment and bonding of the glass microchips I received from Dolomite.
"Previously I waited months for clean room glass processing.
"With Dolomite it was completed within weeks and to a much higher standard".
Dolomite ssys it is now a worldwide leader in this field.
So much so, that in 2005 it won funding from the UK Department of Trade and Industry's Micro and Nano Technology (MNT) Manufacturing Initiative.
This £2m funding has allowed Dolomite to establish excellent microfabrication facilities, with cleanrooms, precision glass processing facilities and applications laboratories.
In addition to this, Dolomite has managed to attract top quality engineering and scientific staff with strong backgrounds across the broad range of disciplines required for success in bringing microfluidics applications to the market, including; chemistry, biotechnology, control system development, electronics, physics and instrument design and supply.
