Dancing Egg

Optical tweezers use the idea similar to l'ou com balla. It consists in placing an egg in a fountain filled with water. When the egg goes over the fountain spout, the latter lifts the egg up and makes it roll over. That's why it's called “the dancing egg.” It's a playful show celebrated the vigil and the Corpus day, principally in the cloister of Barcelona Cathedral, as well as in other catalan public courtyards. The tradition is dated back to 1440.

Consisteix a col·locar un ou dins una pica d'un sortidor, amb aigua a l'interior. Quan l'ou va a parar a damunt del raig d'aigua del brollador, aquest l'enlaira i el fa giravoltar; d'aquí que se'n digui “l'ou com balla”. Es tracta d'un espectacle lúdic que se celebra la vigília i el dia de Corpus, principalment, al Claustre de la Catedral de Barcelona, però també a d'altres patis públics de Catalunya. Aquesta tradició de l'ou com balla data del segle XV, concretament, de l'any 1440.

Projects

1. Raman Spectroscopy of Single Living Cells

Raman spectroscopy permits us to get time- and spatial resolved information on biochemical and biophysical processes in single living cells.

Sphere Above Cell

2. Combining Raman spectroscopy and Photonic Force Microscopy

Correlation of forces measurements with structural and chemical information reveals new insights in mechanics of single living cells.

3. Photonic Force Microscope as a Spectrometer

We study recoil effects due to the fluorescence or Raman emission when active molecules are proximal to, or adsorbed on the PFM probe.

4. Noise-Assisted Effects in Physics and Biophysics Studied by the Technique of Optical Traps

Using optical traps we study the noise assisted phenomena with two sources of noise: a thermal noise and an external correlated noise.

5. Electrophoresis in an optical trap

We study electrical states of single living cells and colloids detecting their response on electrical field of different frequencies.
