A novel method for rapid and sensitive illicit drug screening in biofluids has been developed by employing a paper-based sample collection coupled with ultrasonic desorption-assisted low-temperature plasma ionization mass spectrometry (PBS-LTPI-MS). For optimization, key experimental parameters, such as geometry coordinates, angle, and plasma intensity, were fine-tuned using ketamine as the...
