The phase behavior of biomolecules containing persistent molecular entities is generally limited due to their characteristic size that exceeds the intermolecular force field. Consequently, favorable properties normally associated with the liquid phase of a substance, such as fluidity or processability, are not relevant for the processing of biomolecules, thus hindering the optimal processing of biomolecules. The implied problem that arises is how to convert folded biomolecules to display a richer phase behavior. To alleviate this dilemma, a generic approach to liquefied polysaccharides-based polymers is proposed, resulting in a polysaccharide fluid with a tunable condensed state structure (solid-gel-liquid). Polysaccharide biobased fluids materials transcend the limits of the physical state of the biobased material itself and can even create completely new properties (different processing methods as well as functions) in a variety of polymeric structures. Considering the solvent incompatible high and low-temperature applications, this method will have a great influence on the design of nanostructures of biomolecular derivatives and is expected to transform biomass materials such as polysaccharide biopolymers from traditional use to resource use, ultimately leading to the efficient use of biomass materials and their sustainability.
含有持久性分子实体的生物分子的相行为通常受到限制，因为其特征尺寸超过了分子间力场。因此，通常与物质液相相关的有利特性，如流动性或可加工性，与生物分子的加工无关，从而阻碍了生物分子的最佳加工。由此产生的一个隐含问题是如何使折叠的生物分子表现出更丰富的相行为。为了缓解这一困境，提出了一种基于液化多糖的聚合物的通用方法，得到了一种具有可调凝聚态结构（固体-凝胶-液体）的多糖流体。多糖生物基流体材料超越了生物基材料本身物理状态的限制，甚至可以在各种聚合物结构中创造全新的特性（不同的加工方法以及功能）。考虑到溶剂不相容的高温和低温应用，该方法将对生物分子衍生物的纳米结构设计产生重大影响，并有望将多糖生物聚合物等生物质材料从传统用途转变为资源利用，最终实现生物质材料的高效利用及其可持续性。
