The rapid advancements in healthcare technologies have led to the emergence of innovative diagnostic systems that can provide real-time, continuous monitoring of patients' health [1]. Among the most transformative innovations in this field are biosensors, nanoparticles, and the Internet of Things (IoT), all of which have the potential to revolutionize the way medical conditions are detected, monitored, and managed [2]. Biosensors, devices designed to detect specific biological markers or physiological parameters, have become integral to the modern diagnostic process [3]. With the integration of nanomaterials, these sensors exhibit enhanced sensitivity and specificity, allowing for more accurate and timely detection of a wide range of diseases, from infectious conditions to chronic illnesses [4]. When coupled with IoT technologies, biosensors gain the added benefit of real-time data transmission, enabling healthcare providers to monitor patients remotely and make informed decisions without the need for constant in-person visits [5].
Nanotechnology, which involves the manipulation of materials at the nanoscale, plays a crucial role in enhancing the performance of biosensors [6]. Nanomaterials, such as gold nanoparticles, carbon nanotubes, and quantum dots, offer several advantages over conventional materials, including higher surface area, increased reactivity, and the ability to functionalize their surfaces for targeted interactions [7,8]. These unique properties enable biosensors to achieve high sensitivity, allowing for the detection of biomarkers at lower concentrations and faster response times [9]. The ability to modify the surface chemistry of nanoparticles also facilitates the development of highly specific sensors that can identify biomarkers associated with specific diseases or conditions, thus improving the precision of diagnostics [10].
The integration of IoT into healthcare systems has further amplified the potential of biosensors by enabling seamless communication and data transfer between devices [11]. IoT technologies facilitate the continuous collection, transmission, and analysis of health data, providing real-time insights into a patient's condition [12]. This integration makes it possible for healthcare providers to track patients' health status remotely, offering the opportunity for more proactive and personalized care [13]. For instance, wearable IoT-enabled biosensors can continuously monitor critical parameters such as blood glucose levels, heart rate, blood pressure, and oxygen saturation, allowing for immediate interventions when necessary [14]. This ability to monitor patients in real-time also reduces hospital visits and enables more effective management of chronic conditions, thereby improving overall patient outcomes [15].
