Combining acoustic bioprinting with AI-assisted Raman spectroscopy for high-throughput identification of bacteria in blood [PDF]
, 2022 Identifying pathogens in complex samples such as blood, urine, and wastewater is critical to detect infection and inform optimal treatment. Surface-enhanced Raman spectroscopy (SERS) and machine learning (ML) can distinguish among multiple pathogen species, but processing complex fluid samples to sensitively and specifically detect pathogens remains an

Plasma free bubble cavitation in water by a 2.9 μm laser for bioprinting applications [PDF]
, 2022 We investigate the dynamics of the cavitation bubble induced by 2.9 {\mu}m mid-IR laser pulses (10 ns, 10-50 {\mu}J) resulting in a plasma-free direct fast heating of water due to a strong vibrational absorption. We establish a direct correlation between the laser fluence (up to 6 J/cm^2) and the maximum bubble radius (up to 200 {\mu}m).
