1. Nanopatterning by Swift Heavy Ions
Sammanfattning : Today, the dominating way of patterning nanosystems is by irradiation-based lithography (e-beam, DUV, EUV, and ions). Compared to the other irradiations, ion tracks created by swift heavy ions in matter give the highest contrast, and its inelastic scattering facilitate minute widening and high aspect ratios (up to several thousands).

2. Development of electrochemical sensor and biosensor platforms : detection of therapeutic drugs and heavy metal ions
Sammanfattning : Electrochemical sensors and biosensors combine the sensitivity of electroanalytical methods with the selectivity of a sensor or biosensor surface. The chemical or biochemical component (receptor) in the sensor recognizes an analyte and produces an electrical signal which is proportional to the analyte concentration. LÄS MER
3. Heavy Metal Superantigen : Genetic Regulation of Lymphocyte Activation by HgC12
Sammanfattning : Injections of subtoxic doses of HgCl2 (mercuric chloride) cause a systemic autoimmune disease in genetically predisposed rats and mice. My work was designed to elucidate how HgCl2 induces lymphocyte activation and how the response to HgCl2 is regulated in susceptible and resistant strains. LÄS MER
4. Protein-based capacitive biosensors for the detection of heavy-metal ions
Sammanfattning : Some metal ions, such as copper and zinc, are essential nutrients and catalysts in biochemical reactions. Other metal ions, e.g. cadmium and mercury, are highly toxic elements. LÄS MER
5. Heavy-ion transport codes for radiotherapy and radioprotection in space
Sammanfattning : Simulation of the transport of heavy ions in matter is a field of nuclear science that has recently received attention in view of its importance for some relevant applications. Accelerated heavy ions can, for example, be used to treat cancers (heavy-ion radiotherapy) and show some superior qualities with respect to more conventional treatment systems, like photons (x-rays) or protons.
