IMPETUX WITH BIOMEDICAL RESEARCH

IMPETUX WITH BIOMEDICAL RESEARCH

IMPETUX with the Health Care sector:

IMPETUX is collaborating in the Innovation of the Health Care sector with Photonic Technologies Program designed by SECPHO (Southern European Cluster in Photonics & Optics) and ITEMAS ( Medical Technology Innovation Platform)

The first meeting was on the 1st of April. There, we take the opportunity to explain how optical tweezers can become a key tool for biomedical research.

There will be more meetings like that. You will find more information at the Secpho webpage here

Stay tuned.

Time dependence of trap position (top), force signal (middle) and Ca2+ fluorescence signal (bottom) recorded during a membrane tether pulling experiment. The force and Ca2+ ion channel activity signals exhibit negative correlation.

Fig. 2

Force and displacement data for two beads stimulated at frequencies of 4 Hz and 0.25 Hz. The progressive reduction of the beads displacement is in concomitancy with an increase of the applied force and loading rate.
