coating

Natural polysaccharides such as chitin and chitosan are excellent sources for new materials with exceptional properties. Here we present innovative applications of the biopolymer derived from crustaceans or mushrooms in bulletproof coatings and smart windows.

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.

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.

The topic for september is the application of chitosan for improvement of food products. The perfect reading material for your lunch break.

We present a new interesting publication with chitosan from HMC⁺ for you...

In March 2016, 289 publications about chitosan and chitosan derivative have been released. Most articles investigated chitosan nanoparticels and polymers, as well as chitosan in pharmaceutical preparations. Majority of chitosan research takes place in China (55 articles), USA (36) and India (21). Development of new scaffold materials for in vitro tissue engineering is an important topic for regenerative medicine. Biomaterial scaffolds need to be biocompatible and cell growth supportive.

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.

January opens the publication year 2012 with overall 159 articles about chitosan. Almost one third of the articles was published in China.

China:    56 articles
India:    15 articles
USA:     14 articles
Tawain:   7 articles 
 

So far November is the month with most publications in the year 2011. Overall 168 articles were published.

The three countries with the most publications are again:

China (53 Artikel),
India (20 Artikel) and the
USA (12 Artikel).

The number of publications increased in October. So 144 articles about chitosan were released. Looking at the amount of publications the same countries as in September led the list.
Most publications came from China. In October 40 articles were published there. With 13 published articles India was in second place, followed by the USA with overall 11 publications.

In September a total of 62 articles were published in the field of chitosan. In this month the most publications came from China where 10 articles were published. With 7 articles India was in second place followed by the USA where 6 articles were published.

In May the publication rate of chitosan issues slightly dropped again. 84 articles were published which means six less than in April 2011, but two publications more than in May 2010.

The team of Prof. Maryam Tabrizian from McGill University in Montreal, Canada developed a procedure that might be the basis for the application of donated blood independently from the blood group.

Scientist at the Mississippi South University in Hattiesburg succeded a spectacular development - a self-reparing material when exposed to ultraviolet light. Prof. Marek Urban and Ph.D. student Biswajit Ghosh were researching on a coating, which main components are chitosan and oxetan. From their point of view this priniciple can be of greatest importance for many matrials.
