We are pleased to present this joint special issue of Macromolecular Bioscience and Advanced Materials Interfaces titled “Biointerfaces Biopolymers”. In the last decades there has been an explosion in material science with revolutionary concepts that merge state-of-the-art chemistry, physics, biology, nanoscience technology. Concurrently, basic research biological materials started shed light n...

Recovery of cellulose fibres from paper mill effluent has been studied using common polysaccharides or biopolymers such as Guar gum, Xanthan gum and Locust bean gum as flocculent. Guar gum is commonly used in sizing paper and routinely used in paper making. The results have been compared with the performance of alum, which is a common coagulant and a key ingredient of the paper industry. Guar g...

We developed a quartz crystal microbalance (QCM) based molecular ruler that measures the length of surface immobilized, hydrated biopolymers (DNA and proteins). These biopolymers acted as stakes that solidified surrounding liquid at high frequency vibration in QCM measurements, which led to a simple linear frequency-thickness relation.

In recent years, environmentally friendly and enzymatically biodegradable biopolymers have attracted the attention of researchers. The advantage of these materials is decomposition naturally in nature [1]. Biopolymers are playing important role in nanotechnology. Chitosan is one of the well-known biopolymers and is produced by deacetylation of chitin. The degree of deacetylation directly correl...

With the evolution of single molecule techniques as force-scope optical tweezers, it has become possible to perform very accurate measurements of the elastic properties of biopolymers as e.g. DNA. Nucleic acid elasticity is important in the interaction of these molecules with proteins and protein complexes in the living cell. Mostexperimental and theoretical effort has been aimed at uncover...

One of the critical components of the mechanisms of cell communication and cell computing has been postulated to be spaceand time-organized teleonomic (or goaldirected) shape changes of biopolymers that are driven by exergonic chemical reactions catalyzed by biopolymer shape changes themselves. The generalized Franck-Condon principle resolves the apparent paradox arising when a coupling is atte...
