Desidero innanzitutto ringraziare il Prof. Cremisi per avermi cos`ı calorosamente accolto nel suo laboratorio, offrendomi la straordinaria opportunit`a di lavorare in- sieme ai ricercatori della Scuola Normale Superiore in un ambiente sempre ricco di stimoli e di nuove sfide.
Ho inoltre un profondo debito di gratitudine nei confronti di Luca Pandolfini. Ri- cercatore eclettico e pieno di risorse, nel corso dell’ultimo anno ho avuto il pri- vilegio di conoscerlo e d’apprezzarne la dedizione e la professionalit`a. Desidero ringraziarlo per aver cos`ı attentamente seguito il mio lavoro sperimentale, per i suoi preziosi consigli e per avermi pazientemente guidato attraverso le difficolt`a.
Vorrei quindi rivolgere un particolare ringraziamento ad Antonella per la sua ras- sicurante presenza in laboratorio, la grande generosit`a e l’infinita pazienza nel venirmi in soccorso. Sono inoltre riconoscente a Cristina, Michele e Roberto per avermi permesso di beneficiare liberamente della loro esperienza, per il loro soste- gno ed i loro consigli.
Sono infine grato al Prof. Vignali, alla Prof.ssa Batistoni ed alla Dott.ssa Studer per i loro insegnamenti ed il loro supporto.
