The Use Of Electrospun Nanofibers With Gold And Silver Nanostars For The Detection Of Fentanyl Using Surface Enhance Raman Spectroscopy, The Modification Of Current Gc-Ms Methods To Increase Separation And Detection Of Synthetic Cathinones In Mixtures, Daniel Rubin
FIU Electronic Theses and Dissertations
Many criminal cases involve the use or sale of illicit substances. The forensic analyst has many different techniques they can use to analyze samples to determine which illicit substance is present. This project aims at developing electrospun nanofibers with nanoparticles to analyze fentanyl by surface enhanced Raman spectroscopy, as well as modifying current GC-MS parameters to enhance separation and analysis of synthetic cathinones. Using the fibers with nanoparticles allowed for the detection of fentanyl standards at 1mg/ml while slowing the oven ramp rate and modifying the hold times led to an increase in separation and better fragmentation patterns for determination. …
