Furthermore, the basic concepts of analytical methods to study the characteristics of SMILES nanoparticles, including their size and optical properties, are discussed. The main focus of the thesis concerns the attractive fluorescent properties and effective energy transfer processes of SMILES nanoparticles, contributing to their promising bioimaging applications.\n\nThe aim of the experimental part was to investigate the energy transfer processes from the cyanostar anion complex to dye molecules in SMILES nanoparticles. This was conducted by preparing optically active SMILES nanoparticles containing rhodamine and DAOTA dyes and SMILES nanoparticles with an optically inactive cation. The SMILES nanoparticles containing optically inactive cations were prepared using imidazole and tetrabutylammonium cations to study the cyanostar anion complex. The energy transfer efficiency and the dominant energy transfer mechanism were determined.\n\nThe size of the nanoparticles was determined using dynamic light scattering (DLS) and cryo- transmission electron microscopy (cryo-TEM). Absorption and fluorescence spectroscopy were employed to investigate the fluorescent properties. Fluorescence lifetimes were measured using time-correlated single photon counting (TCSPC).", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2024-06-26T07:34:31Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2024-06-26T07:34:31Z (GMT).
