Results in brief
TWO-Dimensional nanomaterial-based metasurfaces for enhanced Plasmonic Sensing
The convergence of nanotechnology, biology, and photonics opens the possibility of detecting and manipulating atoms and molecules that promises to revolutionize diagnostics and therapy at the cellular and even molecular level. As a result, a large variety of biosensors, which incorporate biological probes coupled to a transducer, have been developed during the last two decades for environmental, industrial, and biomedical diagnostics. Biosensors are usually based on systems that can detect electronic or optical signals in terms of the concentrations of biological molecules, where molecular interactions can be monitoring by the signal change. Useful applications include DNA analysis, glucose concentration test in human blood, and sensing of toxins in the water, food, and atmosphere. Current challenges for biosensors, especially for handheld devices that can be deployed at the point of care, are to improve their detection sensitivity, and reduce their size and operating cost. The rapid development of the fabrication techniques for different types of nanomaterials has allowed many breakthroughs on the optical and electronics properties, e.g., high charge carrier mobility, negative refraction, hyperbolic dispersion. Typical examples are the discovery of monolayer graphene and metamaterial/metasurfaces, which showed to us how the properties and performances for optoelectronic sensing and imaging devices can be improved by engineering the materials at the nanoscale and even atomic scale. They are promising materials for the plasmonic field as the sensing substrate to realize the zero-reflection for the phase singularity. The objective of this project is to design and fabricate ultrasensitive plasmonic biosensors with the integration of atomically thin perovskite nanomaterials on metasurfaces, reaching a detection limit up to 10^-10 refractive index unit (RIU) for the target sample solutions.

Project objective
In the past decade, biosensors have provided an effective way for the physical and chemical science to improve the quality of the life in the modern society. The biosensors are usually based on systems that can detect electronic or optical signals in terms of the concentrations of biological molecules. Thus, it allows the monitoring of molecular interactions from the signal change. Useful applications so far include DNA analysis, glucose concentration test in human blood, sensing of toxins in the water, food and atmosphere. Current challenges for the biosensors are to improve their detection sensitivity and efficiency while with reduced size and operation cost. My research aims to achieve simple, fast and sensitive detection through label-free biosensing technology. For this aim, I will develop a novel plasmonic sensor based on optimized 2D nanostructures with magneto-optic materials for achieving ultra-high sensitivity for the hard-to-identify small biomolecules and explore new physics on the magneto-plasmonic effects generated by the coupling between the 2D nanomaterials and gold/magnetic materials metasurfaces. Miniaturization for commercially portable products embedding those highly sensitive nanostructures will be studied. The proposed research will significantly improve my knowledge in exploiting the optical/magnetic properties of novel plasmonic nanomaterials for enhanced light matter interactions. This project will play a pivotal role for my personal development as an independent researcher and provide me with the unique opportunity to work with experts in the field of materials, electromagnetics and sensing. I will benefit from ideas and inputs from renowned researchers from various scientific disciplines to compliment my background. Moreover, I aim to deliver the related research works though a series of seminars and lectures to present the importance and relevance of utilizing novel nanostructures for sensor development.
