Hybrid Nanomaterials in Biosensors for Advanced Point-of-Care Diagnostics: DNA-, Enzyme-, or Immunosensor-Based, for Healthcare

In the intricate landscape of healthcare, biosensors—whether it be DNA-based, enzyme-based, or immunosensor-based—play a pivotal role. Each type possesses distinct advantages, tailored to specific healthcare applications, target analytes, and diagnostic requirements. Imagine a symphony of precision: rapid, accurate disease diagnosis at the patient’s bedside—the essence of point-of-care (POC) diagnostics. Enter hybrid nanomaterials—the unsung heroes. These nanoscale wonders, which combine distinct types of nanomaterials, offer enhanced sensing capabilities, improved sensitivity, and increased biocompatibility. Their integration into biosensor platforms propels POC advancements, revolutionizing healthcare. This book chapter delves into this symphony, comparing three primary types of biosensors—DNA, enzyme, and immunosensor-based systems containing hybrid nanomaterials. Their potential benefits span wide, their applications limitless. Welcome to a world where nanomaterials dance, and diseases retreat.
