Research Interests

My research is mainly focused on the development of biosensors using functionalized, bioconjugated, fluorescent silica nanoparticles. Surface characterization of the synthesized nanomaterials and the study of their adsorption behavior are other areas of interest. In addition, the following research avenues are explored in different research projects.

  • Heterogeneous catalysis
  • Quantum mechanical and molecular dynamics computational calculations

Another different area I’m currently exploring is chemistry education research and practice.

Ongoing Research Projects

  1. Functionalized nanoparticles for the quantitative detection of bacteria
  2. Development of multifunctional core-shell nanoparticles
  3. Functional materials for algae harvesting
  4. Development of SERS probes for the detection of melamine in milk products
  5. A computational approach for designing vaccine candidates for dengue viruses
  6. Designing a conceptual framework for authentic teaching to facilitate effective learning in secondary schools of Sri Lanka
