   Abstract : The delivery of nucleic acids to cells, in vitro and in vivo, is becoming a realistic approach for intervention with gene expression at a molecular level. It can be used to repair malfunctioning genes or to introduce new functionalities, with the most important application being clinical treatment of human diseases. READ MORE

7. 5. Environment-Sensitive Multifunctional Drug Delivery Systems

   Author : Jian Qin; Mamoun Muhammed; Marcus Textor; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materials chemistry; Materialkemi;

   Abstract : Drug delivery systems (DDS) with multiple functionalities such as environment-sensitive drug release mechanisms and visualization agents have motivated the biomedical community as well as materials chemists for more than a decade. This dissertation is concerned with the development of nanoparticles for multifunctional DDS  to tackle several crucial challenges in these complex systems, including polymeric nanospheres which respond to temperature change, superparamagnetic iron oxide nanoparticles/polymeric composite for magnetic resonance imaging contrast agents and drug carriers, immunoresponse of nanomaterials and injectable magnetic field sensitive ferrogels.
