Tyrosol-functionalized chitosan-gold nanoparticles against fungal biofilms

Fungi of the Candida genus can be responsible for serious skin infections, especially as biofilms. To find an alternative treatment method for fungal biofilms, chitosan-gold nanoparticles were coupled with the quorum sensing molecule Tyrosol in the study presented here.

Fluorescence immunoassay for detection of pathogens

Listeriosis is a foodborne infectious disease caused by the pathogen Listeria monocytogenes and is particularly serious for pregnant women and immunocompromised persons. The pathogen is spread mainly through spoiled and contaminated food or animal feed. Methods for the detection of Listeria monocytogenes (LM) on surfaces in the food industry have been developed to control the spread of the pathogen, but these are time-consuming and require special equipment. In the presented study, a fluorescence sandwich immunoassay was developed using a chitosan cellulose nanocrystal (CNC) membrane to detect Listeria monocytogenes on surfaces.

Publications in June 2017 - Chitosan-based coatings for dental implants

The development of a strong bond between implant surface and the surrounding bone substance, called osseointegration is important for successful integration of a dental implant. The coating of dental implants with chitosan is a promising approach to enable an accelerated and improved integration. In the following, we present two publications about chitosan-based coatings for dental implants.

Publications in May 2017 - Functional coatings with chitosan

Functional coatings are applied to improve resistance of implants like artificial heart valves or coronary stents against various impacts in the human body. One problem is the formation of biofilms on the implant surface, which limits communication of the implant with the surrounding area and might induce inflammatory reactions. In addition, nature of the implant material can promote the formation of blood clots, which leads to blocked arteries.

Publications in May 2015

166 articles about chitosan were published in May 2015. In the rank of nations scientists from China gained with 39 publications the leading position, followed by India (16), the US (12) and Italy (11). The research priorities focused on nanoparticles, evaluation studies and pharmaceutical preparations.
