16. Breast Tomosynthesis: Aspects on detection and perception of simulated lesions
Sammanfattning : The aim of this thesis was to investigate aspects on detectability of simulated lesions (microcalcifications and masses) in digital mammography (DM) and breast tomosynthesis (BT). Perception in BT image volumes were also investigated by evaluating certain reading conditions. LÄS MER
17. Magnetic Nanoparticle Based Biosensors for Pathogen Detection and Cancer Diagnostics
Sammanfattning : This thesis describes several magnetic nanoparticle (MNP)-based biosensing strategies which take advantage of different magnetic sensors, molecular tools and nanotechnologies. Proposed biosensors can be classified into three groups, i.e., immunoassay-based, molecular amplification-based, and nanoparticle assembly-based. LÄS MER
18. Silicon Nanowire Based Sensors for Bacterial Tests
Sammanfattning : Rapid and reliable antibiotic susceptibility testing (AST) is urgently required to diagnose bacterial infectious diseases and avoid antibiotic misuse, providing valuable information on the efficacy of antibiotic agents and their dosages for treatment. However, the currently employed phenotypic ASTs normally demand the growth of bacteria into colonies, which usually takes more than two days. LÄS MER
19. Development of high temperature SiC based field effect sensors for internal combustion engine exhaust gas monitoring
Sammanfattning : While the car fleet becomes increasingly larger it is important to lower the amounts of pollutants from each individual diesel or gasoline engine to almost zero levels. The pollutants from these engines predominantly originate from high NOx emissions and particulates, in the case when diesel is utilized, and emissions at cold start from gasoline engines. LÄS MER
20. Studies of MISiC-FET sensors for car exhaust gas monitoring
Sammanfattning : The increasing size of the car fleet makes it important to find ways of lowering the amounts of pollutants from each individual diesel or gasoline engine to almost zero levels. The pollutants from these engines predominantly originate from emissions at cold start, in the case when gasoline is utilized, and high NOx emissions and particulates from diesel engines. LÄS MER
