  1. 1. Detection of Amphetamine with Graphene Quantum Dots

    University essay from KTH/Tillämpad fysik

    Author : Carl Fredrik Åslund; [2021]
    Keywords : Graphene quantum Dots; Amphetamine; Sensor; GQD; Grafen kvantprickar; Amfetamin; Sensor; GQD;

    Abstract : Amphetamine abuse is an enduring problem in many developed nations, including Sweden. It causes lasting damage both to its users and in the form of increased strain on healthcare services. It is therefore critical that police be equipped with the tools necessary to rapidly and accurately identify any samples in order to combat this scourge. READ MORE

  3. 2. The use of graphene quantum dots as detection elements in nanomaterials-based sensors for forensic applications

    University essay from KTH/Tillämpad fysik

    Author : Xiaofan Ma; [2021]
    Keywords : Graphene Quantum Dots; Amphetamine; Cocaine; Chemical Sensor; Forensic Drugs; Grafenkvantprickar; amfetamin; kokain; kemisk sensor; rättsmedicinska läkemedel;

    Abstract : The large-scale abuse and addiction of narcotics such as amphetamine and cocaine have become a global problem. In this project, we innovatively use graphene quantum dots (GQDs) as a fluorescent sensor to detect and quantify amphetamine and cocaine. This technology will have broad forensic application prospects. READ MORE

  4. 3. Biosensor based on immobilized amine transaminase for detection of amphetamine

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Clara Öh; [2020]
    Keywords : amine transaminases ATA ; enzyme immobilization; biosensor; covalent immobilization; ionic immobilization; amphetamine; histidine-tagged enzyme; Poly methyl methacrylate PMMA ;

    Abstract : Amine transaminases (ATA) catalyse the transfer of an amino group from one molecule and replaces a ketone or aldehyde with the amino group, the amino group on the amino-donor is replaced with a ketone or aldehyde. This enzyme, ATA from Chromobacterium violaceum, has previously been used to catalyse the reaction involving amphetamine, therefore, it might be possible to use this enzyme to convert amphetamine and the product absorbs in the UV spectrum and can therefore be measured spectrophotometrically.
