Sensitive detection of cathinones and their adulterants in street samples using electrochemical fingerprinting

Electrochemical detection of MDMA and 2C-B in ecstasy tablets using a selectivity enhancement strategy by in-situ derivatization

“…The applicability of portable electrochemical sensors in the forensic drug testing field is demonstrated for several common drugs of abuse such as cocaine [18][19], heroin [20] and ketamine [21]. Specific electrochemical profiles can also be established for NPS, either as individual compounds [22][23] or for specific classes such as cathinones [24]. Since electrochemical screenings are rapid and may be applied simultaneously using an array of electrodes, selectivity issues from identical electrochemical profiles can be overcome by application of subsequent electrochemical strategies.…”
