Miniaturized platforms for the detection of single-nucleotide polymorphisms.

Conventional methods for detecting single-nucleotide polymorphisms (SNPs), the most common form of genetic variation in human beings, are mostly limited by their analysis time and throughputs. In contrast, advances in microfabrication technology have led to the development of miniaturized platforms that can potentially provide rapid high-throughput analysis at small sample volumes. This review highlights some of the recent developments in the miniaturization of SNP detection platforms, including microarray-based, bead-based microfluidic and microelectrophoresis-based platforms. Particular attention is paid to their ease of fabrication, analysis time, and level of throughput.

LabArray: real-time imaging and analytical tool for microarrays.

UNLABELLED: Microarrays have been used to perform high-throughput genetic analyses such as single-nucleotide polymorphisms detection and microbial genome analysis. Some of these analyses require real-time monitoring of the hybridization signals with respect to a varying experimental condition, such as temperature. However, current microarray imaging and analysis packages typically do not possess such real-time capabilities. Therefore, microarray image analyses are often time-consuming and labour-intensive. LabArray was developed to expedite such processes by enabling real-time monitoring of microarray signals.
