“…However, it has already been shown that ePTFE exhibits high resistance to protein adsorption compared to PET, even upon 48 hours of incubation [23]. Besides, the nanometer dimensions of BNC fibres, the structural elements, result in a larger surface area thereby facilitating the strong interaction between cellulosic moieties with surrounding compounds or proteins [24]. Due to the fibre structure and the porosity of BNC surface, it might therefore be possible that the BNC grafts exhibited distinct protein adsorption properties, despite their hydrophilic nature, which needs further investigation.…”

There is an increasing need for small diameter vascular grafts with superior host hemo-and cytocompatibilities, such as low activation of platelets and leukocytes. Therefore, we aimed to investigate whether the preparation of bacterial nanocellulose grafts with different inner surfaces has an impact on in vitro host cytocompatibility. Methods We have synthesized five different grafts in a bioreactor, namely open interface surface (OIS), inverted (INV), partially air dried (PAD), surface formed in air contact (SAC) and standard (STD) that were characterized by a different surface roughness. The grafts (length 55 mm, inner diameter 5 mm) were attached to heparinized polyvinyl chloride tubes, loaded with human blood and rotated at 37˚C for 4 hours. Then, blood was analyzed for frequencies of cellular fractions, oxidative products, soluble complement and thrombin factors. The results were compared to clinically approved grafts made of polyethylene terephthalate and expanded polytetrafluoroethylene. Additionally, blood platelets were labelled with 111 Indium-oxine to visualize the distribution of adherent platelets in the loop by scintigraphy. Results SAC nanocellulose grafts with the lowest surface roughness exhibited superior performance with <10% leukocyte and <50% thrombocyte loss in contrast to other grafts that exhibited >65% leukocyte and >90% thrombocyte loss. Of note, SAC nanocellulose grafts showed lowest radioactivity with scintigraphy analyses, indicating reduced platelet adhesion.

“…Recently, studies on the design and development of nanostructured materials have gained both scientific and technological interest in several disciplines (Mendoza and Rodríguez-López 2007;Habibi et al 2010;Abdul Khalil et al 2014;Andrade et al 2015;Magalhães et al 2017;Satyanarayana et al 2017). Due to their size, nanostructures exhibit unique properties that make their use attractive in various applications in which both synthetic and natural materials have been incorporated (Corrales 2015).…”

“…In fact, reports are available regarding possible markets for cellulose nanocrystal enabled products (Cowie et al 2014). The study and development of new materials based on nanostructured biomaterials, particularly those of lignocellulosic origin, has been the subject of many research works (Ahuja and Kumar 2009;Brinchi et al 2013;Rosli et al 2013;Reyes et al 2014;Thakur 2014;Andrade et al 2015;Kumode et al 2017;Satyanarayana et al 2017).…”

“…(Zeni et al 2016). The properties of NCCs depend on several factors, such as sources of cellulose, reaction time, temperature, and the acids used for hydrolysis (Abe et al 2007;Ahuja and Kumar 2009;Beck-Candanedo and Gray 2005;Elazzouzi-Hafraoui et al 2008;Brinchi et al 2013;Rosli et al 2013;Reyes et al 2014;Andrade et al 2015;Kumode et al 2017;Satyanarayana et al 2017;Thakur 2014). These unique physicochemical properties and broad application perspectives have attracted substantial interest from scientific and industrial researchers (Peng et al 2011).…”

High purity cellulose nanocrystals (NCCs) were obtained through the generation of various nanoparticle suspensions from different hydrolysis conditions of soluble grade cellulose (α-cellulose) prepared from huizache wood (Acacia farnesiana L. Willd.). These NCCs exhibited different surface morphologies and properties. Hydrolysis was carried out using both sulfuric and hydrochloric acids, while the methodology was based on 23 factorial designs of experiments. The obtained nanocrystals were characterized for particle size distribution, morphology, size of the NCCs, residual surface charge of the nanoparticles, and chemical composition using various experimental techniques. The two acid hydrolysis procedures produced NCCs suspensions that exhibited a unimodal or bimodal pattern of the Gaussian type, but differed in their properties. Average NCCs particle size obtained by hydrolysis with different concentrations (60 to 65%), at different temperatures (45 to 55 oC) and treatment times (45 to 65 mins) with H2SO4 acid and HCl acid were approximately 100 to 260 nm and between 75 nm to 512 nm, respectively, indicating influence of concentration and treatment time with both acids. Also, residual load analysis of sulphate groups in the NCCs suspensions in producing NCCs by H2SO4 hydrolysis revealed a minimum load of 39 mmol/kg and a maximum of 505 mmol/kg of NCCs.
