   Abstract : Do metal particles (including particles of pure metals, alloys, metal oxides and compounds) pose a hazard or risk to human health? In the light of this question, this thesis summarizes results from research conducted on metal particles, and describes the elaboration and implementation of an in vitro test methodology to study metal release from particles through corrosion and dissolution processes in synthetic biological media relevant for human exposure through inhalation/ingestion and dermal contact. Bioaccessible metals are defined as the pool of released metals from particles that potentially could be made available for absorption by humans or other organisms. READ MORE

4. 2. Electrochemical (bio-)sensors operating in human physiological fluids

   Author : Carolin Psotta; Sergey Shleev; Magnus Falk; Evgeny Katz; Malmö universitet; []
   Keywords : biosensor; bacteria; enzyme; sensor; physiological fluid;

   Abstract : This thesis is focused on developing electrochemical (bio-)sensors specifically designed to detect biomolecules and bacteria in human physiological fluids. A more comprehensive understanding of their performance can be obtained by exposing the sensors to real human physiological fluids. READ MORE

5. 3. Hand eczema and contact allergy in healthcare work

   Author : Nils Hamnerius; Yrkes- och miljödermatologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; occupational dermatitis; healthcare worker; hand eczema; allergic contact dermatitis; rubber additives; diphenylguanidine; medical gloves;

   Abstract : Hand eczema is common in healthcare workers. Besides wet work, healthcare work also implies exposure to contact allergens. Occupational hand exposures have changed in recent years owing to implementation of hand hygiene procedures including an increased use of medical gloves. READ MORE

6. 4. Bacterial sensors and controllers based on organic bioelectronics

   Author : Karen Butina; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Bacterial infections and contaminations are worldwide problems, leading to morbidity and mortality, food waste and economic losses in a variety of industries. The situation is aggravated by the increased occurrence of antibiotic-resistant strains, identified by the WHO as one of the biggest threats to development, food security and public health today.
