Novel Synthetic Opioids in Oral Fluid Analytical Methods and Prevalence

Febrero 2021

This webinar will discuss the analytical methodology developed and validated to identify and quantify novel synthetic opioids and traditional opioids in oral fluid. The presenter will also discuss targeted and non-targeted approaches using liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods for detection of fentanyl- and non-fentanyl related novel synthetic opioids. Additionally, this webinar with cover sample preparation techniques for isolating synthetic opioids with various chemistries and structures.

Preemptive Approach to Combatting and Characterizing Emerging Synthetic Opioids

Febrero 2021

This webinar seeks to describe how preemptive synthesis and characterization of potent psychoactive substances from the literature can aid forensic scientists in the identification of unknowns appearing in samples emerging from illicit markets. Additionally, the presenter seeks to provide understanding of how gaps in pharmacological knowledge of old drugs can be exploited to find new emerging synthetic drugs.

Emerging Methods for Body Fluid Analysis

Enero 2021

The NIJ Forensic Technology Center of Excellence hosted a panel of subject matter experts to discuss emerging methods for body fluid analysis. This webinar is in three sections: 1) Proteomics and its potential in high-throughput forensic laboratories. 2) Surface Enhanced Raman Spectroscopy and the rapid detection and identification of body fluids. 3) MicroRNA, mRNA, and the development of a microfluidic device used to detect and differentiate body fluids from an unknown sample.

Expanding Research to Examine the Impacts of Forensic Science on the Criminal Justice System

Diciembre 2020

In 2004, the National Institute of Justice created the social science research on forensic sciences (SSRFS) research program to explore the impact of forensic sciences on the criminal justice system and the administration of justice. Much of the early research from the SSRFS program focused on DNA processing and the use of DNA in investigations and prosecutions.

Dual System Youth: At the Intersection of Child Maltreatment and Delinquency

Diciembre 2020

Across the country, child welfare and juvenile justice systems now recognize that youth involved in both systems (i.e., dual system youth) are a vulnerable population who often go unrecognized because of challenges in information-sharing and cross system collaboration. In light of these challenges, national incidence rates of dual system youth are not known.
