講演要旨

Our research focuses on developing innovative imaging and biosensing platforms that integrate nanotechnology and photonics for a wide range of biomedical applications, from oncology to infectious disease detection. Here I will delve into two distinct types of platforms.
First, I will introduce lens-free on-chip microscopy, a powerful alternative to traditional optical microscopy, that addresses key limitations associated with objective lenses, such as limited field of view. Using computational techniques based on holography and fluorescence, these on-chip microscopy systems enable wide-area imaging and high-throughput analysis, while offering a cost-effective (~$100) and portable solution. I will discuss the design of on-chip microscopy and its utility towards a wide range of applications, particularly for screening anti-cancer drugs and detection of pathogens.
In the second part, I will shift focus to the development of ultrabright nanoparticles tailored for high-resolution deep-tissue structural and functional imaging. These nanoparticles consist of an inorganic perovskite nanocrystal core enclosed by multiple polymer shells, which can encapsulate fluorescent sensors and drug molecules. These multi-core-shell nanoparticles are being utilized in tasks like labeling cells and mapping various chemical analytes in cells and tissues for early diagnostics and therapy monitoring.
