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.

Here we present a stochastic biogeochemical model for the formation, transformation and mineralization of natural organic matter (NOM). The model is agent-based, with each software agent representing a single molecule of defined composition. Molecular properties and reactivities are estimated from composition and environmental parameters. Environmental parameters including temperature, pH, ligh...

An innovative material constituted of a natural biopolymers blend (Funori) from Gloiopeltis algae and Ca(OH)2 nanocrystals was developed to consolidate linen fibers for cultural heritage conservation preventing future degradation due the alkaline reservoir by Ca(OH)2. The procedure extract Funori reliable reproducible consolidation performances aged Funori/Ca(OH)2 smart system were showed highl...

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...
