EPSRC PhD Studentship in Integrated sensing technology for point-of-care diagnostics

该项目的目的是利用半导体物理学、光子学和生物化学中的几种新兴技术开发新一代的生物传感器。该设计基于芯片实验室方法，其中光学激发、传感元件和检测器制造在同一化合物半导体芯片上，仅需要电驱动和读出。传感器的构建块是光子晶体，即光学器件，其中介电材料的周期性结构被设计成定制与光的相互作用，以创建独特的光学特性。该项目涉及生物传感器开发的不同方面，从不同组件的建模到使用最先进的光谱学和电气测试设施表征其性能。

The aim of this project is to develop a new generation of miniaturised biosensors capitalising on several emerging technologies in semiconductor physics, photonics, and biochemistry. The design is based on a lab-on-a-chip approach, where the optical excitation, sensing elements, and detectors are fabricated on the same compound semiconductor chip, requiring only electrical drive and read out. The building blocks of the sensor are photonic crystals, i.e. optical devices where periodic structures of dielectric materials are engineered to tailor the interaction with light, to create unique optical properties. The project involves different aspects of the development of the biosensor, from the modelling of the different components to the characterisation of their performance using state of the art spectroscopy and electrical testing facilities.
