Department of Computer Science, College of Computer and Information Sciences, King Saud University, Riyadh, 11543, Saudi Arabia.
The Internet of Medical Things (IoMT) has revolutionized healthcare by bringing real-time monitoring and data-driven treatments. Nevertheless, the security of communication between IoMT devices and servers remains a huge problem because of the inherent sensitivity of the health data and susceptibility to cyber threats. Current security solutions, including simple password-based authentication and standard Public Key Infrastructure (PKI) approaches, typically do not achieve an appropriate balance between security and low computational overhead, resulting in the possibility of performance bottlenecks and increased vulnerability to attacks.

Development of sensitive and cost-effective strategies for detecting influenza viruses is crucial to combat the spread of infectious diseases. In this study, a novel trans-dimensional nanocoral gold foam (NCGF) was fabricated on screen-printed carbon electrodes using hydrogen template electrodeposition method. This unique structure, with interconnected large and small pores, significantly increased the specific surface area and stability of the sensor.
