Growth of monolayer MoS₂ on Optical Fibers via CVD for Neurological Applications

The atomically thin two-dimensional (2D) materials have opened new avenues for addressing the complex challenges associated with neurological research and medical applications. One such development in this context is the utilization of optical fibers (OFs) coated with 2D materials, which can transmit electrical and optical signals back and forth. The integration of 2D materials with OFs can exceptionally revolutionize clinical diagnostics and cure combining the virtues of both OFs (optical signal transmission) and 2D materials (electrical signal transmission). However, the controlled and defect-free coating of 2D materials over OF’s surface is still challenging. Herein, we propose the direct coating of molybdenum sulfide (MoS₂) over OF using chemical vapor deposition (CVD). This breakthrough holds great promise for enhancing the capabilities of OFs-based technologies in the field of neuroscience, offering a powerful tool for future research and applications.
