1. Superparamagnetic iron oxide nanoparticles (SPIONs) as a multimodality imaging probe for sentinel nodes : Design and Preclinical Evaluation
Abstract : Breast cancer and malignant melanoma disseminate through the lymphatic system and the first metastases arise in one or two regional, sentinel lymph nodes (SLNs) draining the primary tumour site. Therefore, identification and characterization of the SLNs is of major importance for cancer staging and for choice of therapy in patients. READ MORE

2. Engineered core : shell nanoparticles: synthesis, characterisation, and biocompatibility studies
Abstract : Superparamagnetic iron oxide nanoparticles (SPIONs) have emerged as promising contrast agents for Magnetic Resonance Imaging (MRI). Some SPIONs are already approved for clinical use. Coating of these nanoparticles with an additional biocompatible layer serves to improve the colloidal stability and biocompatibility. READ MORE

3. Environment-Sensitive Multifunctional Drug Delivery Systems
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.

4. Applications of nanotechnology in neuroscience : functionalized superparamagnetic nanoparticles as contrast enhancers in experimental magnetic resonance imaging
Abstract : Magnetic resonance imaging (MRI) is a noninvasive imaging technique that helps clinicians not only to diagnose but also to plan the treatment of invasive surgery and actually treat medical conditions. Superparamagnetic iron oxide nanoparticles (SPIONs) are a family of MRI contrast agents that improves MRI sensitivity/specificity. READ MORE

5. Ultrasound Contrast Agents Loaded with Magnetic Nanoparticles : Acoustic and Mechanical Characterization
Abstract : The current methodologies in body scanning diagnostic uses different simultaneous imaging modalities like Ultrasound (US), magnetic resonance imaging (MRI), single photon emission tomography (SPECT) and positron emission tomography (PET). The field requires combination of different modalities for effective use in clinical diagnostics. READ MORE
