Introduction

Biosensors are analytical devices that combine a biological component with a physicochemical detector to identify and measure biological or chemical substances. Over the past few decades, biosensors have revolutionized fields such as healthcare, environmental monitoring, food safety, and biotechnology. These devices provide rapid, highly sensitive, and cost-effective methods for detecting biomolecules, making them invaluable tools for diagnostics and research. This article explores the fundamental principles of biosensors, their classification, working mechanisms, applications, challenges, and future prospects. A biological recognition element (e.g., enzymes, antibodies, nucleic acids, or cells) that interacts specifically with the target analyte. Converts the biological response into a measurable signal, typically electrical, optical, or thermal. Processes the signal and provides a readable output, often displayed digitally. The efficiency of a biosensor depends on its specificity, sensitivity, response time, and stability. These factors are crucial for ensuring accurate and reliable detection. Biosensors are classified based on their bioreceptors, transduction mechanisms, and application areas. Detect genetic material for disease diagnostics or forensic applications. PCRbased biosensors for viral detection [1,2]. Use living cells to detect toxic substances. Drug screening assays in pharmaceutical research. Use synthetic single-stranded DNA or RNA molecules (aptamers) for high specificity detection. Measure electrical signals generated by biochemical reactions.

Description

Detect changes in light properties due to analyte interaction. Surface Plasmon Resonance (SPR) biosensors used in drug discovery. Detect mechanical changes like mass variation using quartz crystals. Measure heat changes in biochemical reactions. Metabolic activity detection in clinical diagnostics. The bioreceptor binds specifically to the target molecule. The transducer converts the biochemical reaction into a measurable signal. The signal is amplified and processed to provide a quantifiable output. In a glucose biosensor, glucose oxidase (enzyme) reacts with glucose, producing an electrical signal proportional to the glucose concentration. Biosensors have widespread applications across multiple fields. Diabetes patients use electrochemical glucose biosensors for self-monitoring. COVID-19 rapid antigen tests rely on biosensor technology. Biosensors for cancer biomarker detection help in early diagnosis. Smartwatches integrated with biosensors monitor heart rate, oxygen levels, and stress levels. Biosensors are used in pharmaceutical research for drug efficacy testing. Biosensors detect heavy metals, pesticides, and pathogens in drinking water. Sensors detect harmful gases like carbon monoxide and nitrogen oxides. Biosensors assess agricultural soil for toxins and pollutants. Used to detect spoilage indicators in perishable food items [3,4]. Optical biosensors detect harmful chemicals in fruits and vegetables. Biosensors optimize fermentation and microbial growth in biotechnology industries. Helps in screening for harmful drug side effects.

Conclusion

Some biosensors struggle with detecting low-concentration analytes in complex samples. Bioreceptors like enzymes and antibodies degrade over time, affecting performance. Advanced biosensors require expensive materials and technology. Lack of global regulatory frameworks for biosensor approval. Developing compact, user-friendly biosensors remains a challenge for researchers. Use of nanomaterials like graphene, carbon nanotubes, and quantum dots to enhance sensitivity. AIbased biosensors improve accuracy by analysing large datasets. Smart biosensors in clothing and accessories for real-time health monitoring. Portable biosensors for rapid disease detection in remote areas. Biosensors tailor treatment plans based on individual patient profiles. Microfluidic biosensors enable ultrasensitive analysis of biological samples. Wireless connectivity for remote patient monitoring.
