The green fluorescence of the proteins has a reward
The authors of the study ensure that biologists will be able to implement this technique in experimental set-ups and obtain the cell temperature as another observable detail. In 2008, when Osamu Shimomura, Martin Chalfie and Roger Y. Tsien won the Nobel Chemistry Prize for discovering and developing GFP, they resolved many complications in biomedical research.
In the field of molecular biology, different techniques have been suggested to monitor internal cell temperature, these researchers found limitations in measuring the intensity and spectrum of its fluorescence.
Furthermore, the option of measuring intracellular activity could establish the basis to develop a field that has not been widely studied: thermal biology at cellular level.
According to the authors of the study, the following step is to improve the method's sensitivity and resolution. In order to achieve that, the researchers work to fine tune the properties of the fluorescent proteins and optimise the detection method of its 'thermometer'.
