Ultra-short laser ablation of Biological tissue – Investigation of application of femtosecond pulses in dentistry by introducing a  minimally invasive concept for treatment of carious lesions.

Ultra-fast laser mass spectrometry of biological molecules - In our approach, we combine ultrashort laser ablation with time-of-flight mass spectroscopy (TOF-MS). Our work demonstrates the sensitivity of TOF-MS for the identification of the biomolecular species present in laser-ablated material from hard tissues. Performingfemtosecond laser ablation at 800nm altered the chemical composition of the ablated tissue and yielded the highest number of characteristic ions.
