Abstract
The rapid advancement of nanotechnology-based materials has led to groundbreaking developments across various fields, with biosensors emerging as powerful tools for point-of- care diagnostics. These biosensors offer numerous advantages, including exceptional selectivity, sensitivity, rapid results, affordability, and user-friendliness without requiring specialized personnel. Notably, electrochemical and paper-based biosensors have exhibited significant potential in detecting small molecules, such as illicit drugs and viral particles. To further enhance accessibility, the integration of smartphones as readout devices, empowered by specialized applications and color-assisted analysis, has revolutionized biosensor technology. We present our latest research findings on the development of nanoparticle-based biosensors designed to detect a wide range of biomolecules. Our investigations encompass abuse drugs like cocaine, methamphetamine, and synthetic cannabinoids, along with viruses such as Covid-19, and target molecules including pesticides. By harnessing the unique properties of diverse nanoparticles, such as magnetic, gold, silver, and polymeric structures loaded with specific dyes, we have achieved remarkable outcomes, generating reliable signals and vibrant colors that rival traditional sensing methodologies. Capitalizing on the extensive capabilities of smartphones, we have successfully implemented advanced color and electrical signal analysis through both existing and tailor-made applications. Furthermore, our exploration extends to the realm of proof-of-concept prototypes, including the development of wearable watches for the detection of illicit drugs. These innovative devices exemplify the transformative potential of nanotechnology and biosensor integration, offering a portable and discreet solution for real-time monitoring and detection. By highlighting the pivotal role of nanomaterials in biomedical applications, this presentation underscores the tremendous opportunities for advancing personalized diagnostics and therapies. The marriage of nanotechnology and smartphones holds immense promise in reshaping the boundaries of
