Molybdenum disulfide (MoS2), as one of the most promising next-generation two-dimensional (2D) nanomaterials, has showed great potential for developing ultrasensitive biosensors. Though research advances have been made, whispering-gallery-mode (WGM) biosensing, which is one of most sensitive optical biosensing mechanisms, has not been realized on 2D MoS2, despite its superior optoelectronic properties. This is largely due to the difficulty of fabricating MoS2 optical rings. To tackle this challenge, we propose, to integrate the rolled-up nanotechnology with 2D MoS2 nanolayer, for developing the first MoS2-based rolled-up optofluidic ring resonator (MRU-OFRR) biosensor. Thanks to the MoS2's high quantum efficiency, high-refractive index, and atomically-thin structures, the developed MRU-OFRR can provide a much higher quality factor (Q-factor) than those of existing passive rolled-up microtube ring resonators and therefore allows ultrahigh sensitivity of diseases biomarker detection.

The PhD studentship is available for three years subject to satisfactory progress by the student. The award covers tuition fees for three years (currently equivalent to RMB 80,000 per annum) and provides a monthly stipend of 5,000 RMB as a contribution to living expenses. It also provides up to RMB 16,500 to allow participation at international conferences during the period of the award. It is a condition of the award that holders of XJTLU PhD scholarships carry out 300-500 hours of teaching assistance work per year. The scholarship holder is expected to carry out the major part of his or her research at XJTLU in Suzhou, China. However, he or she is eligible for a research study visit to the University of Liverpool of up to three months, if this is required by the project.
