2. 1. Towards improved drinking water safety : the use of in vitro bioassays to optimize treatment processes and assess chemical hazards

   Author : Maria Yu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Drinking water safety has been primarily dependent on the monitoring of only a limited number of individual chemicals via chemical analysis, which is insufficient to characterize the myriad of hazardous chemicals present in water. Effect-based methods (EBMs) using in vitro bioassays are useful in that they evaluate biological effects from all the known and unknown chemicals in the water and draw on toxicological principles.

   Abstract : Exploring and visualizing biological and pathological processes in living cells are useful for both fundamental research and applications. An understanding on the molecular level for these processes with focus on tracking biomarkers, collecting information about their surroundings, and uncovering essential molecular pathways and functions in live cells are of vital interest for cell biological study and clinical diagnosis application.

   Abstract : This thesis describes work done towards realizing on-scalp magnetoencephalography (MEG) based on high critical temperature (high- T c) superconducting quantum interference device (SQUID) sensors. MEG is a non-invasive neuroimaging modality that records the magnetic fields produced by neural currents with good spatial and high temporal resolution. READ MORE

7. 5. Creating Ultrafast Biosensors for Neuroscience

   Abstract : Neuronal communication is the basis for all our brain function and relies on regulated exocytosis, a cell function that involves release of quantal amounts of neurotransmitters into the gap space between interconnected neurons to serve as chemical signals. To study exocytosis, which is a fast process that occurs on the timescale of sub-milliseconds to milliseconds, a toolbox of analytical methods has been developed where the electrochemical based techniques offer quantitative and sufficient high temporal recording speed.
