WebFeb 1, 2007 · The first widely recognized in vitro collagen alignment was performed by Elsdale and Bard [30] via a drainage technique, which involves gravity-driven flow. This technique was extended by Mosser et al. [31] to prepare very high-concentration collagen matrices that display a variety of liquid crystalline types of order. WebAug 1, 2008 · Collagen liquid crystals are obtained at acidic pH where repulsions between positively charged residues are large enough to prevent aggregation and maintain a liquid state. The possibility to stabilize fluid collagen phases into dense gels, by fibrillogenesis, then established a relevant link with living tissue morphologies [7], [8•].
