Where Biology, Chemistry and Photonics meet.
Intracellular Temperature Measurments
This project is based on the elucidating and understanding why cancer cells are warmer compared with non-cancer cells. This general objective is meant to present intracellular temperature as a new paradigm in molecular biology utilizing the last advances of biophotonics and nanotechnology.
It is expected that intracellular temperature will become fully utilized and be considered a meaningful variable for many biological applications and provide a more accurate description of intracellular environments than what is currently available

Photodynamic and photothermal therapy
The objectives in this project include the development of new phtodynamic/photothermal therapy agents.
Together with that, a deeper understanding of the cell death mechanisms induced by these agents is also part of the objectives in cell culture as well in animal models.

Develop the new nanothermomethers
This project includes the development and presentation of new probes that can report the nano-scale measurements of temperature: Nanothermometers. The information obtained from these nanothermometeres are utilized to fully understand the biological implications of intracellular temperature and the measurement of temperature in other scientific research fields.
