1. 1. Phase Modulation Two-Photon Microscopy of Hybrid Halide Perovskite

   Författare :Qi Shi; NanoLund: Centre for Nanoscience; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phase modulation; two-photon microscopy; perovskite; trap; carrier recombination;

   Sammanfattning : Recently, intense research activities have been focused on solution-processed hybrid lead halide perovskite semiconductors which are being developed for the solar-cell, light emitting diode (LED), and lasing applications. To optimize and fabricate a competitive perovskite-based optoelectronic device, the fundamental studies of the electronic structure, photo-generated carrier dynamics as well as the photoluminescence (PL) & photocurrent (PC) response are necessary and of great significance.

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photodynamic therapy; PDT enhancement; Nitric oxide; NO-based PDT; Targeted drug delivery; Galectin-3; mTHPP; Cyclodextrin; CD-mTHPP conjugate; PpIX AuNP combination; Two-photon microscopy; FLIM; Cell phototoxicity; Ex vivo skin;

   Sammanfattning : The increasing incidences of cancer and related deaths call for the development of new and improved treatment modalities. Photodynamic therapy (PDT) today is an alternative to conventional treatments, but has limitations. This thesis explores different nanosystems with aim to improve PDT focusing on spectroscopic and ex vivo studies. LÄS MER

5. 4. Multiphoton Microscopy Targeting Tissue Development. Towards the real-time imaging of epidermal differentiation

   Författare :Monika Malak; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multiphoton microscopy; fluorescence lifetime imaging; epidermal differentiation; reconstructed human epidermis; organ-on-a-chip; intrinsic fluorescence;

   Sammanfattning : The development of novel organ-on-a-chip models calls for methodologies, which will allow the study of tissue development and pharmacological outcome in real-time. Multiphoton microscopy (MPM) has been proposed as a suitable technique for noninvasive imaging of live specimens, utilizing intrinsic tissue fluorescence. LÄS MER

7. 5. Laser Scanning Multiphoton Microscopy – Focusing on Fluorescence Correlation Spectroscopy and Fluorescence Lifetime Imaging for Biomedical Applications

   Författare :Jeemol James; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser scanning multiphoton microscopy; intrinsic cellular fluorophores.; fluorescence correlation spectroscopy; fluorescence lifetime imaging; melanoma metastasis;

   Sammanfattning : Laser scanning multiphoton microscopy (MPM) is considered as a non-invasive technology for three-dimensional imaging of complex biological tissues. The quantitative potential of the MPM is not investigated as much as qualitative imaging. LÄS MER
