  2. 11. In vitro characterization of nanodrugs at model lipid membranes

    Author : Rickard Frost; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; in vitro screening; nanomedicine; drug delivery; drug carrier; supported lipid bilayer; QCM-D; nanoparticle; cell membrane;

    Abstract : The use of nano-sized drug carriers to improve the efficiency of drug delivery has become well established during the past decades. New nanoparticle (NP) formulations for the administration of biopharmaceuticals (e.g. proteins and peptides) emerge at an increasing rate and the need for methods to evaluate their properties is expanding.

  4. 12. Hydrogels of Poly(vinyl alcohol) and Nanocellulose for Ophthalmic Applications : Synthesis, Characterization, Biocompatibility and Drug Delivery Studies

    Author : Gopi Krishna Tummala; Albert Mihranyan; Natalia Ferraz; Cecilia Persson; Jonas Lindh; Che Connon; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanocellulose; poly vinyl alcohol ; hydrogel; cornea regeneration; therapeutic lens; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Abstract : Hydrogels are commonly used materials in ophthalmic care as contact lenses, bandage lenses, corneal implants, and cornea regeneration scaffolds. Hydrogels can be produced by physical, chemical, or radiation crosslinking of hydrophilic polymers. READ MORE

  5. 13. Controlled Release Gel Formulations for Mucosal Drug Delivery

    Author : Mattias Paulsson; David Attwood; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; Galenisk farmaci; Pharmaceutics;

    Abstract : Drug delivery to nasal or ocular mucosa for either local or systemic action faces many obstacles – these routes are protected by effective mechanisms. Gel formulations with suitable rheological and mucoadhesive properties increase the contact time at the site of absorption. READ MORE

  6. 14. Interactions of Mucins with Biopolymers and Drug Delivery Particles

    Author : Olof Svensson; Malmö högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mucin; chitosan; lactoperoxidase; multilayer; mucoadhesion; nanoparticles; ellipsometry;

    Abstract : The main components in the mucous gels apart from water are mucins, which are proteins with high molecular weights and an abundance of negatively charged oligosaccharide side chains. The aim of the investigations was to characterize interactions between mucins and other proteins that are present in the mucous gel, and also between mucins and components used in pharmaceutical formulations.

  7. 15. Geopolymer-based drug formulations for oral delivery of opioids

    Author : Bing Cai; Susanne Bredenberg; Håkan Engqvist; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Opioid therapy for chronic pain generally use controlled release formulations to deliver analgesic drugs around-the-clock. Controlled release dosage forms can enlarge the therapeutic effect by controlling the rate and site of release. However, with high drug content, opioid formulations are easily targeted for non-medical use. READ MORE
