Applications of Cutting-Edge Biosensors in Healthcare and Biomedical Research

Biosensors are remarkable devices that convert biological reactions to chemical compounds into measurable signals, allowing for specific detection of target analytes. The classification of biosensors is based on the type of bioreceptor or transducer used. They have diverse applications in environmental monitoring, detection of toxins, pharmaceuticals, prosthetics, biotechnology, and biomedical engineering, with a crucial role in monitoring soil, water, and food quality. In the field of health and biomedicine, biosensors have undergone significant advancements in diagnosis and treatment of diseases by providing highly accurate results. This chapter focuses on the advancements and applications of biosensors in various biotechnological domains

A Novel Electrochemical Sensor for the Detection of Reactive Red Dye to Determine Water Quality

In this study, tragacanth gum/chitosan/ZnO nanoprism-based electrochemical sensors were prepared for sensing reactive dyes in water. To use an electrochemical sensor, a ~250 nm-sized ZnO nanoprism was synthesized via ultrasonic-assisted green synthesis method, using tragacanth gum and chitosan polymer blend as a matrix. The electrochemical properties of tragacanth gum/chitosan/ZnO nanoprisms were compared against reactive red 35, reactive yellow 15, and reactive black 194. The electrochemical measurement results indicated that prepared tragacanth gum/chitosan/ZnO nanoprism-based electrochemical sensor detected 25 ppm reactive red 35 in 1 min at room temperature. This study reveals new high-potential novel tragacanth gum/chitosan/ZnO nanoprism-based sensing material for the detection of reactive red dye-consisted wastewater with high sensitivity and short response time
