1. Fullerene γ-Cyclodextrin Complexes
Sammanfattning : The fullerenes, C60 and C70, can form inclusion complexes with .gamma.-cyclodextrin as the host. The complexes are formed by refluxing a water solution of . LÄS MER
2. Investigations of New Biomimetic Transamination Systems and Inclusion Complexation with Cyclodextrins
Sammanfattning : Two new transamination systems are described. The first example is a dibenzo[a,d]- cycloheptene containing system, designed to accomplish a [1,3]-hydride transfer. Several catalysts have been examined for this purpose. tris-Pentafluorophenyl borane was found to be the most efficient catalyst. LÄS MER
3. An alkaline active maltooligosaccharide forming alpha-amylase from Bacillus halodurans
Sammanfattning : The East African Rift Valley contains a number of soda lakes, which represent some of the most stable, naturally occurring alkaline environments on earth. Alkaliphilic microorganisms found in these habitats have attracted a great interest due to their ability to produce extracellular enzymes that are active and stable at high pH values for industrial applications.

4. An Alkaline Active Cyclodextrin Glycosyltransferase from an Alkaliphilic Bacillus agaradhaerens
Sammanfattning : Soda lakes represent the most stable naturally-occurring alkaline environments on Earth and harbour a diverse population of alkaliphiles. Alkaliphilic microorganisms have attracted a great interest due to their ability to produce extracellular enzymes that are active and stable at high pH values. LÄS MER
5. Exploring nanosystems for biomedical applications focusing on photodynamic therapy and drug delivery
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
