  2. 1. Development of Non-leaching Antibacterial Approaches on Cellulose-based Substrates and Their Mechanisms

    Author : Chao Chen; Monica Ek; Josefin Illergård; Stefan Spirk; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Layer-by-layer; antibacterial; cellulose materials; Chemical Engineering; Kemiteknik;

    Abstract : The layer-by-layer (LbL) technique is becoming a powerful tool that has been applied in many surface coatings and functionalizations in recent years. It has many advantages including a fast and mild process, the flexibility of choice of substrate, and the easiness to scale-up. READ MORE

  4. 2. Antibacterial effects of nitrite in urine

    Author : Stefan Carlsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Nitrite; nitrate; nitric oxide; urinary tract infection; catheter-associated urinary tract infection; antimicrobial; Escherichia coli.;

    Abstract : Urinary tract infections (UTI`s) are among the most common conditions causing individuals to seek medical care. In addition, catheter-associated infections account for most of the hospital-acquired UTI´s and is also a major source of resistant nosocomial pathogens. READ MORE

  5. 3. The synthesis of dendritic hydrogels and inorganic nanoparticles and their application as antibacterial and imaging materials

    Author : Yanmiao Fan; Michael Malkoch; Annelie Brauner; Mauri Kostiainen; KTH; []
    Keywords : antibacterial hydrogels; dendritic polymers; dendrimers; silicon nanoparticles; cellulose nanofibrils; drug-resistant bacteria; wound dressings; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : AbstractThe overuse and misuse of conventional antibiotics has caused increased prevalence of drug-resistant bacteria, the infections of which cause high mortality and economic losses per year. It is therefore crucial to develop new technologies and treatments for infections caused by drug-resistant bacteria. READ MORE

  6. 4. Production, purification and characterization of antibacterial biomolecules from an alkaliphilic Bacillus

    Author : Abolghasem Danesh; Bioteknik; []
    Keywords : ;

    Abstract : Forty alkaliphiles, which were isolated from samples collected in Eastern Africa, have been screened for production of antibacterial compounds. One of these isolates, Bacillus halodurans B20, was able to produce a prominent amount of antibacterial activity against a Gram-positive bacteria on agar plates [paper I] and selected for further study.
