In plain language

Biosensor devices consist of a bioreceptor, transducer, and detector designed to detect and measure parameters of primary metabolites, immunological molecules, and various other materials. Among these, piezoelectric biosensors demonstrate strong efficiency in sensitivity, response time, selectivity, and linearity. Recent developments have introduced nanobiosensors that assist in transduction and detect biomolecules with high sensitivity. These nanobiosensors can be either homogeneous or heterogeneous and operate within the sensing mechanisms of biosensing technology. Across biomedical domains, nanobiosensors are applied to decrease toxins in products and support disease diagnostics. This review examines the different types of nanobiosensors, their biomedical applications, the associated challenges, and preferred solutions in biomedical technology.

Key takeaways

  • Biosensors rely on a combination of a bioreceptor, transducer, and detector to measure metabolites, immunological molecules, and other substances.
  • Piezoelectric biosensors offer high efficiency characterised by good sensitivity, response time, selectivity, and linearity.
  • Nanobiosensors can be homogeneous or heterogeneous and provide high sensitivity during transduction.
  • Nanobiosensors are used to reduce poison in products, diagnose diseases, and serve various biomedical functions.

Why it matters

Detecting biomolecules accurately is essential for health monitoring and safety. Biosensors and nanobiosensors offer responsive, sensitive tools to identify disease markers and reduce toxic substances in commercial products. Understanding how these tools function helps advance effective diagnostic systems and safer consumer goods.

Commercialisation angle

The work highlights applications in disease diagnostics and toxic reduction in consumer products, which could benefit healthcare providers and quality control industries. As a descriptive overview of types, challenges, and solutions, the abstract represents early-stage conceptual synthesis rather than a validated, near-market device.

Abstract

Abstract Biosensor devices are composed of bioreceptor, transducer and detector that detect and aid in measuring parameters of some primary metabolites, immunological molecules and many more materials. These devices are of various types including piezoelectric which exhibit high efficiency based on sensitivity, response time, selectivity and linearity. Currently, newly developed nanobiosensors help in transduction and are employed to sense biomolecules bearing high sensitivity. Nanobiosensors also could be homogeneous or heterogeneous in nature and equally function in sensing mechanism of the biosensing technology. Thus, different nanobiosensors are greatly utilized to reduce poison in products, disease diagnostics and in many biomedical applications. Based on all these factors and the positive impact of using these devices; nanobiosensor types, applications, challenges and preferred solution in biomedical technology were considered and discussed in this work.
