Article Synopsis
- Phenols are common industrial pollutants found in sectors like pharmaceuticals and agriculture, often released untreated, necessitating effective detection methods.
- Current detection techniques like spectrophotometry and chromatography are costly and complex, highlighting the need for a simpler, affordable solution.
- This study presents a new method using low-cost colorimetric paper-based sensor strips to detect phenols in water using the Folin-Ciocalteu reagent, achieving high recovery rates with promising detection limits.
Paper-based sensors, often referred to as paper-based analytical devices (PADs), stand as a transformative technology in the field of analytical chemistry. They offer an affordable, versatile, and accessible solution for diverse analyte detection. These sensors harness the unique properties of paper substrates to provide a cost-effective and adaptable platform for rapid analyte detection, spanning chemical species, biomolecules, and pathogens.

It introduces an innovative approach using graphene oxide (GO) and GO-decorated polyethersulphone (PES) membranes to efficiently remove these ions from contaminated water. The process involves integrating GO into PES membranes to enhance their adsorption capacity.

However this therapy has its own limitations due to the development of resistance, over a period of time. One of the possible causes of the development of resistance to the therapy with EGFR inhibitors could be the simultaneous activation of parallel pathways.
