Identification and classification of ATS in oral fluid based on Ag nanoassemblies on Si surface doped with Au nanobipyramids

“…The high prevalence and associated morbidity and mortality of ATS abuse is now a major public health issue, with a sharp increase in overdose deaths related to ATS. [1] According to the Substance Abuse and Mental Health Services Administration, the number of people over the age of 12 misusing ATS increased from 1.7 million in 2016 to 5.1 million wordwide in 2020. Therefore, there is a growing need to the control ATS abuse.…”

Identification and classification of ATS in oral fluid based on Ag nanoassemblies on Si surface doped with Au nanobipyramids

“…Over the past decade, misuse of amphetamine-type stimulants has grown significantly worldwide. The high prevalence and associated morbidity and mortality of ATS abuse is now a major public health issue, with a sharp increase in overdose deaths related to ATS 1 . According to the Substance Abuse and Mental Health Services Administration, the number of people over the age of 12 misusing ATS increased from 1.7 million in 2016 to 5.1 million wordwide in 2020.…”
