Microfluidics-Based Nanobiosensors for Healthcare Monitoring.

Efficient healthcare management demands prompt decision-making based on fast diagnostics tools, astute data analysis, and informatics analysis. The rapid detection of analytes at the point of care is ensured using microfluidics in synergy with nanotechnology and biotechnology. The nanobiosensors use nanotechnology for testing, rapid disease diagnosis, monitoring, and management.

Recent advances in enzymatic biosensors for point-of-care detection of biomolecules.

Late state-of-the-art analytical methodologies in chromatography, spectroscopy, and electroanalysis have been developed to meet the challenges of changing environmental and health issues. The modern trends in developing new protocols emphasize economic, portable, nano, or even smaller sample sizes and less time-consuming processes. This has led to the development of technology-based biosensors which meet most of the above requirements.

A hydrolase with esterase activity expressed from a fosmid gene bank prepared from DNA of a North West Himalayan glacier frozen soil sample.

Screening of 20,000 clones of a fosmid gene bank, constructed from DNA extracted from North West Himalaya (NWH) glacier soil sample, using functional approach identified 10 esterase/lipase-producing clones. Of these, a clone designated pFG43 with an insert size of 45 kb which produced the highest concentration of enzyme (467.43 U/mg) was sequenced.
