1. 1. Automated HER2 Scoring of Breast Cancer Tissue using Upconverting Nanoparticle Images

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Adam Belfrage; Alexander Wik; [2022]
   Nyckelord :HER2-scoring; image analysis; interpretability; digital pathology; computer aided pathology; whole slide imaging; ASCO-guidelines; singular value decomposition; shape models; Bayesian classification; Biology and Life Sciences; Medicine and Health Sciences; Technology and Engineering; Mathematics and Statistics;

   Sammanfattning : Computer aided pathology is becoming more and more of a requirement within pathology due to increased demand of individualised treatments and personalised medicine. Because of the advance of digital pathology in recent years, where a high resolution camera acquire images of microscope slides, pathologists can now assess tissue samples in digital images. LÄS MER

   Sammanfattning : The name Upconverting nanoparticles refers to a novel category of luminescence emitters that are capable of generating visible luminescence upon excitation with noncoherent and longer wavelength monochromatic near-infrared light, at excitation fluence rates as low as 1-103 W/cm2. This unique optical behaviour is of great interest to researchers as it could potentially allow for virtually autofluorescence free luminescence imaging of living tissue. LÄS MER

4. 3. Development of an Upconverting Nanoparticles Quantum Yield Measurement System

   Kandidat-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Författare :Meng Li; [2016]
   Nyckelord :UCNPs; upconverting nanoparticles; QY; quantum yield; fluorescence; luminescence; Physics and Astronomy;

   Sammanfattning : Fluorescence imaging is a growing biomedical technique; it can be used to localize the luminescent biomarkers inside the tissue. Lanthanide-doped upconverting nanoparticles (UCNPs) are promising luminescent probes for multiple applications in biophotonics. They allow acquiring autofluorescence-free recordings with high spatial resolution. LÄS MER

7. 5. Nd-doped Upconverting Nanoparticles for Deep Tissue Imaging

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Författare :Hugo Söderlund; [2014]
   Nyckelord :fluorescence imaging; Upconverting nanoparticles; biophotonics; Nd-doped comparison; Physics and Astronomy;

   Sammanfattning : During the last decade, upconverting nanoparticles (UCNPs) doped with rare-earth (RE) ions have been extensively studied in the field of biophotonics. Due to their unique properties of anti- Stokes shifted luminescence and with excitation and emission wavelengths optimal for biomedical imaging, they have become an interesting class of fluorescent contrast agents.
