Phosphorylated bacterial cellulose for adsorption of proteins

Bacterial cellulose as a material for wound treatment: Properties and modifications. A review

“…Additionally specific functional groups may lead to better affinity towards secondary components, including bioactive macromolecules or cell lines, improving BC biocompatibility. A larger adsorption of metal ions (Oshima et al, 2008) and proteins (Oshima et al, 2011) onto phosphorylated BC and a greater adsorption of hemoglobin (Niide et al, 2010) onto quaternary ammonium BC was reported in comparison to similarly modified plant-derived cellulose. Sulfate group introduction of up to 0.42% of OSO 3 -groups improved BC interaction with xyloglucan (Pirich et al, 2015).…”

“…For example, phosphorylation of BC results in better protein adsorption. All tested proteins (e.g., lysozyme, hemoglobin, myoglobin and albumin) showed pronounced adsorption rates onto an anionic phosphorylated BC surface under pH conditions lower than their isoelectric points (Oshima et al, 2011). Lin et al (2015a) showed an increase in adsorption quantity of bovine serum albumin with the increase of carboxymethyl functional groups in the BC substrate.…”

Characterisation and properties of homo- and heterogenously phosphorylated nanocellulose

“…The latter are usually applied as homogeneous chemical reactions using mainly toxic reagents and organic solvents that result into partial or total disruption of the original fibrous integrity. The synthesis of phosphorus cellulose derivatives has thus been performed in various solvents [dimethyl sulphoxide (DMSO)-methylamine, DMAc-LiCl, SO 3 -triethylamine, formic acid, trifluoroacetic acid, N,N-dimethylformamide (DMF)-N 2 O 4 , paraformaldehyde, trimethylchlorosilane-DMF, urea in melt or aqueous-NaOH], with many variants of phosphorous compounds (phosphoric and phosphinic acids, phosphorus oxoacids, phosphorus pentoxide, amidophosphates, alkyl or aryl derivatives of phosphorous acids) (Granja et al, 2001a(Granja et al, , 2001bIsogai & Atalla, 1998;McCormick, Callais, & Hutchinson, 1985;Nifant'ev, 1965;Oshima et al, 2011;Petreus, Bubulac, Petreus, & Cazacu, 2003;Ramos, Assaf, El Seoud, & Frollini, 2005). The highest substitution degree (DS between 1 and 2.8) of water soluble phosphorylated cellulose was obtained from the reaction of MCC with phosphorous acid/urea, either in melt (Inagaki, Nakamura, Asai, & Katsuura, 1976;Suflet et al, 2006) or subsequently to microwave activation (Gospodinova et al, 2002).…”

“…The creating of negatively charged phosphoric groups (such as cellulose phosphate or cellulose phosphite) on cellulose is a well-known strategy when producing materials applicable in orthopaedics (Petreus et al, 2014), biomedical (Granja et al, 2001a(Granja et al, , 2001bLi, Wang, Liu, Xiong, & Liu, 2012;Mucalo, Kato, & Yokogawa, 2009), textile (Aoki & Nishio, 2010;Tzanov, Stamenova, & Cavaco-Paulo, 2002), plastics (as flame-retardants' fillers) (Gérard, Fontaine, & Bourbigot, 2010), fuel cell (Ma & Sahai, 2013) bio-chemical separation (as cation exchangers) (Suflet, Chitanu, & Popa, 2006), and other applications (such as protein adsorbents) (Oshima, Taguchi, Ohe, & Baba, 2011).…”

Functional nanomaterials through esterification of cellulose: a review of chemistry and application

“…Thus, cellulose phosphates were used as metal-chelating polymers, as cation exchange materials and as adsorbents for the treatment of pollution (Bezerra et al 2014;Illy et al 2015;Li et al 2002;Oshima et al 2008;Padilha et al 1995). Furthermore, phosphorylated BNC was found to be effective as an adsorbent for proteins with a high adsorption capacity via electrostatic interaction (Oshima et al 2011).…”
