Introduction

Trong-Nghia Le, Ph.D., is an Assistant Professor in the Department of Chemistry at National Taiwan Normal University (NTNU). A specialist in analytical chemistry and nanotechnology, Dr. Le focuses on the development of quantum-enhanced biosensors and stimuli-responsive materials. His work is characterized by the integration of fundamental chemical principles with clinical diagnostic needs, specifically in the realm of infectious diseases and oncology. With numerous SCI-indexed publications, a book chapter, and editorial contributions, he is dedicated to advancing materials science and analytical chemistry in biomedical applications.

The TN Le Research Group is a multidisciplinary laboratory at NTNU dedicated to the rational design of functional nanomaterials for ultrasensitive analytical applications. The laboratory’s mission is to bridge the gap between material science and clinical translation. By leveraging the unique physical properties of nanocarbon materials—specifically Fluorescent Nanodiamonds (FNDs)—the group develops diagnostic platforms that achieve unprecedented detection limits. The lab also pioneers the synthesis of smart polymer architectures for targeted drug delivery and environmental remediation. With access to state-of-the-art facilities, the group remains committed to providing a high-level training ground for the next generation of researchers in nanobiotechnology.


Research Topics

The group's research is categorized into three primary pillars:

  1. Quantum-Enhanced Biosensing & Diagnostics
    Focusing on the use of Nitrogen-Vacancy (NV) centers in Fluorescent Nanodiamonds to develop Spin-Enhanced Immunoassays. This technology enables ultrasensitive detection of biomarkers for cancer, tuberculosis, and other viral pathogens (e.g., SARS-CoV-2 antigens and Dengue Virus NS1 proteins), exceeding the signal-to-noise ratios of standard optical assays.
  2. Stimuli-Responsive Nanomedicine
    Utilizing pH- and ROS-responsive block copolymers for precision oncology. These nanocarriers are designed to encapsulate potent chemotherapeutics, ensuring selective release within the acidic microenvironment of tumors, thereby maximizing therapeutic index and minimizing systemic side effects.
  3. Functional Materials for Environmental Analytics
    The synthesis of multifunctional fluorogenic probes and catechol-functionalized copolymers for the selective sensing and sequestration of heavy metal ions, addressing critical challenges in water purification and environmental monitoring.
