Study on a novel portable urine analyzer based on optical fiber bundles

A low-cost compact blood enzyme analyzer based on optical sensing for point-of-care liver function testing

“…In 2018, Saleh et al 7 developed a blood urea nitrogen dry chemical detection system based on the Odroid technology. In the same year, Liu et al 8,9 described a novel urine dry chemical analyzer based on an optical structure composed of fiber bundles. The use of optical fibers effectively reduces the influence of ambient light on the detection results, providing a highly measurable horizontal resolution.…”

“…No previous reports of small, hand-held analytical devices that quantify blood enzymes using dry-chemical strips have been published to the best of our knowledge. Although many reports of dry chemistry analyzers exist, 4,8–10,14 most have focused on urinalysis rather than serum enzymes. Here, we demonstrate the proposed BEA's ability to measure ALT activity in whole blood samples with photochemical test strips using reflectometry for colorimetric quantification of enzyme activity.…”
