Recent Advances in Biosensor Technologies for Point-of-Care Urinalysis.

Area of Science:

• Biomedical Engineering
• Clinical Chemistry
• Analytical Chemistry

Background:

• Human urine is a valuable, non-invasive source for health status indicators.
• Conventional urinalysis methods like dipstick tests are widely used but have limitations.
• Dipstick tests lack sensitivity, selectivity, reusability, and quantitative accuracy.

Purpose of the Study:

• To review biosensor technologies for urine biomarker detection.
• To identify alternatives to conventional dipstick urinalysis.
• To discuss the potential of biosensors for point-of-care (POC) applications.

Main Methods:

• Review of existing literature on biosensor technologies for urinalysis.
• Analysis of biosensors targeting common urine biomarkers.
• Evaluation of challenges for translating biosensors into POC devices.

Main Results:

• Biosensors show potential to enhance sensitivity and quantitative analysis in urinalysis.
• Various biosensor platforms can detect key urine biomarkers.
• Significant challenges remain in developing robust and user-friendly POC urinalysis devices.

Conclusions:

• Biosensor technology offers a promising avenue to improve upon dipstick urinalysis.
• Further development is needed to overcome limitations for successful POC translation.
• Future biosensors could revolutionize routine clinical diagnostics through urine analysis.
