Abstract
We report the synthesis of functionalized nanodots as potential powerful blockers of solute transport through a chitoporin. Ultrasmall silica nanocapsules with a diameter of ∼ 6 nm were coated with chitooligosaccharides to be used as a “lid” binding to the opening of the chitoporin VhChiP of Vibrio campbellii. Efficient blocking is attributed to the adequate size of the nanodots and their functionalization with oligochitosan, which has strong affinity towards the Vibrio chitoporin. This strategy paves the way towards the development of nanomaterials for blocking other porins.
期刊介绍:
Colloids and Surfaces B: Biointerfaces is an international journal devoted to fundamental and applied research on colloid and interfacial phenomena in relation to systems of biological origin, having particular relevance to the medical, pharmaceutical, biotechnological, food and cosmetic fields.
Submissions that: (1) deal solely with biological phenomena and do not describe the physico-chemical or colloid-chemical background and/or mechanism of the phenomena, and (2) deal solely with colloid/interfacial phenomena and do not have appropriate biological content or relevance, are outside the scope of the journal and will not be considered for publication.
The journal publishes regular research papers, reviews, short communications and invited perspective articles, called BioInterface Perspectives. The BioInterface Perspective provide researchers the opportunity to review their own work, as well as provide insight into the work of others that inspired and influenced the author. Regular articles should have a maximum total length of 6,000 words. In addition, a (combined) maximum of 8 normal-sized figures and/or tables is allowed (so for instance 3 tables and 5 figures). For multiple-panel figures each set of two panels equates to one figure. Short communications should not exceed half of the above. It is required to give on the article cover page a short statistical summary of the article listing the total number of words and tables/figures.
