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

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

   Abstract : 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.

4. 2. Non-linear Optical Microscopy and Spectroscopy for Biomedical Studies

   Author : Stina Guldbrand; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Two-Photon Excitation Microscopy; Fluorescence Correlation Spectroscopy; Multiphoton Luminescence; Human Skin; Gold nanoparticles;

   Abstract : This thesis is based on the application of non-linear optical microscopy and spectroscopy techniques within biomedical research. Non-linear optical microscopy gives the possibility of exciting fluorophores using near infrared light. READ MORE

5. 3. Exploring nanosystems for biomedical applications focusing on photodynamic therapy and drug delivery

   Author : Vladimir Kirejev; Göteborgs universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE
