Our invention has introduced the use of polydivinylbenzene (PDVB) as the support for the solid phase polypeptide synthesis (SPPS). Its morphology facilitates the formation of longer polypeptide chains and increases the purity and selectivity of the final product. It can be used with greener solvents, therefore improving the production process from both an economic and environmental point of view.
Dry PDVB has a high proportion of mesopores and a very high specific surface area. In the swollen (working) state, its porosity very little depends on the type of the solvent used for coupling, at variance with conventional supports. These features allow for: a good loading capacity; the formation of longer polypeptide chains with high selectivity and purity; the substitution of conventional coupling solvents, such as N,N-dimethylformamide (DMF), with solvents with a minor environmental impact, such as acetonitrile.
The use of PDVB for SPPS is therefore an opportunity to improve the economic outcome and lower the environmental impact of the polypeptide production process.

  • Colorimetric sensor array for pH measurement

    The invention is a novel pH-meter based on Colorimetric Sensor Arrays (CSA), that surpasses the current limits of the CSA pH-meters, such as single use, relatively slow reaction times and inaccurate pH measurements both in acidic and basic ends of[...]

  • Enzyme treatment for bioplastic recycling

    This technology aims to improve the hydrolysis of bioplastics though the use of microbial enzymes that efficiently hydrolyze polyesters in bioplastic materials. In contrast to cellulosic sugar cane-based materials, starch-based bioplastics and polylactic acid (PLA) items can remain undegraded after[...]

  • Electrically and Mechanically Modular Electrostatic Accelerator with Optical Power Supply

    Low energy accelerators are used in industry and research to generate ion beams suitable for various purposes. This foreseen accelerator overcomes some of the limitations present in state-of-the-art accelerators. In fact, it allows the construction of an accelerator using a[...]
