The incredible shrinking lab
The collection, preparation, and analysis of chemical compounds using miniaturized devices are appealing for many reasons: the use of smaller reagent volumes can reduce the time needed to synthesize and analyze a product, the amount of chemical waste produced and the overall costs can be reduced by performing chemical reactions in these ‘lab-on-a-chip’ devices, and compact devices also allow samples to be analyzed at the point of need rather than at a centralized laboratory. For these reasons, chemists are now using these devices to create new molecules and materials, and biologists are employing these devices to study complex biological problems. Furthermore, labs on chips offer ‘point-of-care’ diagnostic abilities that could revolutionize medicine.
To highlight our interest in this exciting field, the July 27th issue of Nature contains an Insight (a collection of topical articles and reviews) which discuss the history, design, current applications, and the promising future of these ‘lab-on-a-chip’ devices:
The origins and the future of microfluidics (Whitesides)
Scaling and the design of miniaturized chemical-analysis systems (Janasek et al.)
Cells on chips (El-Ali et al.)
