Abstract: Advances in technology opened many doors, increased opportunities in various research fields, and helped create tools and devices required for many analyses. One of them is microarray technology. It is widely used in numerous research areas including infection biology, detection of small noncoding RNAs, microarray-based gene expression profiling, and many more. Microarray implementation in molecular diagnostics and their use as diagnostic devices are considered a step closer to precision medicine. Further advances in microarray technology can potentially help with the identification of new pathogens, improvement in medicine, and better drug delivery.
