Biomedical applications of electrospinning: drug delivery

Electrospinning technique offers numerous possibilities in drug delivery applications, by controlling the material (organic, inorganic, biodegradable or non-biodegradable‚Ķ), the delivered drug or the loading method. In this article, we present an overview of the drug delivery applications of electrospinning. Fiber materials: Biodegradable and non-biodegradable materials behave differently regarding drug release. Non-biodegradable materials release drug mainly… Continue reading Biomedical applications of electrospinning: drug delivery

Sol-gel coatings, a safe alternative to chrome plating

Since the beginning of the 20th century, hexavalent chromium derivates have been used to prevent corrosion and to improve the adherence of further coatings on zinc, magnesium, steel and aluminum alloys. Chromium (VI), or hexavalent chromium, is one of the most stable oxidation states of chromium. It very seldom occurs in nature and most hexavalent… Continue reading Sol-gel coatings, a safe alternative to chrome plating
