1. 16. Fluorescence Lifetime Measurement using Time Correlated Single Photon Counting

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Kemisk fysik

   Author : Mohammad Bilal Akhtar; [2010]
   Keywords : Chemistry;

   Abstract : A time correlated single photon counting (TCSPC) setup is built to measure the fluorescence decay of samples, such as solar cell materials. TCSPC is a sensitive technique for measuring fluorescence decays on nanosecond time scale and longer. READ MORE

3. 17. Synthesis and characterisation of ZnO nanoparticles.An experimental investigation of some of their size dependent quantum effects

   University essay from Institutionen för materialkemi

   Author : T. Jesper Jacobsson; [2010]
   Keywords : ZnO; nanoparticles; quantum dots; Sol-gel; Time resolved UV-Vis spectroscopy; fluorescence; Raman; Phonon spectrum; Synthesis; XRD;

   Abstract : ZnO nanoparticles in the size range 2.5–7 nm have been synthesised by a wet chemical method where ZnO particles were grown in basic zinc acetate solution. The optical band gap increases when the size of the particles decreases. READ MORE

4. 18. Au Nanoparticles as Substrates in Developing Simple and Sensitive Immunoassay for PSA

   University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

   Author : Pradeep Kumar Thalla; [2009]
   Keywords : immunoassay; sensor; gold nanoparticles; fluorescence; optical properties;

   Abstract : The current project work aims to develop a simple and sensitive immunoassay for prostate specific antigen (PSA) by using changes of fluorescence of gold nanoparticles with varying coverage of proteins. In this work we attempted to investigate the changes in optical properties caused by coating the nanoparticles with antibody-antigen complex. READ MORE
