The escalating environmental and public health threats posed by pesticide-contaminated water sources and underutilized cellulose-rich waste demand urgent sustainable solutions. This study presents an eco-friendly multiplex colorimetric sensing platform that concurrently addresses these dual challenges by repurposing recycled cellulose derived from recycled office paper. The system integrates a 3D-printed cassette with a semi-interpenetrating polymer network …

Contemporary medical diagnosis relies on sensors, particularly enzyme-based electrochemical biosensors, to detect disease markers due to their high specificity and sensitivity. However, enzymes as biomolecules denature over time, causing the sensor being less reliable. This research aims to develop hydrogels capable of decreasing the rate of enzyme denaturation in order to extend a lifetime of …

Bacterial cellulose (BC) or well-known as Nata de coco is a natural material with many beneficial physical properties such as biocompatibility, hydrophilicity and high porosity. Herein this research, composite hydrogels have been developed by incorporating carboxymethyl cellulose (CMC) into BC to improve re-swelling property after drying. Gold nanoparticles (AuNPs) were embedded within the BC/CMC composite …
