Two-Dimensional TMD: The Future of Healthcare Technology?

In recent years, two-dimensional materials such as transition metal dichalcogenides (TMD) have gained significant attention for their unique properties, including large surface area and high surface sensitivity, as well as their electrical, optical, and electrochemical properties. These properties make TMD a promising platform for biosensing, which is critical for disease prevention and diagnosis in public health. 

A research team recently conducted a comprehensive review of the state-of-the-art methods used to modulate the properties of TMD and their applications in biosensing. The team found that TMD can serve as an atomically thin platform for energy storage and conversion, photoelectric conversion, catalysis, and biosensing, due to its wide band structure and unusual optical properties. In addition, TMD can be produced in large quantities at a low cost, making it a cost-effective option for biomedical applications. In public health, non-invasive monitoring of biomarkers, such as serotonin, dopamine, cortisol, and epinephrine, is essential for diagnosing psychological diseases. Biosensors play a critical role in the diagnostics, environmental monitoring, and forensic industries by allowing healthcare professionals to quickly and accurately assess a person's stress levels and diagnose psychological diseases. The research team reviewed the use of TMD as a functional material for biosensing and the different approaches to modulating its properties, including electric, optical, and electrochemical sensors. Despite the remarkable potential of TMD-based biosensors, many challenges still need to be solved before they can make a real impact in public health. The research team recommends several possible research directions, including the use of machine learning to reduce testing time and improve the database of biomolecules and TMD pairs, surface modifications to improve the activity of TMD-based composites, and the development of low-cost, low-temperature manufacturing methods to prepare TMD. 

As the key technical issues are solved, the devices based on TMD will be promising candidates for new healthcare technologies. The potential applications of TMD in public health are vast and could play a significant role in disease prevention and diagnosis in the future. The research team's findings provide a valuable contribution to the field and suggest exciting opportunities for further research and development.
