Smartphone-based portable photoelectrochemical biosensing system for point-of-care detection of urine creatinine and albumin

Abstract

Creatinine and albumin are crucial biomarkers for health monitoring and their ratio in urine is an effective approach for albuminuria assessment. Herein, to address the challenges of point-of-care and efficient...

Proficiency Testing Program for Screening Drug Testing Laboratories in the Philippines, 2009-2019

“…It has been widely used in laboratories for teaching urinalysis concepts 5 , and analysis of creatinine and albumin. 6 For PT purposes, it is prepared by dissolving certain amounts of salts, urea, creatinine, acids, and bases (Merck, Darmstadt, Germany) in ultrapure water (18.2 MΩ•cm). Yellow color food dye (obtained from a local supermarket) is added to give its urine-like color.…”

P-EcStat: A Versatile Design of Photoelectrochemical and Electrochemical Sensing System with Smartphone Interface via Bluetooth Low Energy

“…Recent advancements in PEC measurement systems are promising, exemplified by the portable lactate detection system developed by José L. Bott-Neto et al [53]. Similarly, Alexander Scott et al [54] and Zhenghan Shi et al [55] have reported PEC systems designed for POC applications. However, these designs often cater to specific purposes and lack the versatility required for broader PEC research despite the similar characteristics of both methods, which can complement each other due to their merits during the development phase of sensor materials.…”
