Easy scalable and sustainable route to antibacterial surfaces

An Italian research group, specialized in nanotechnology and Colloidal Processing, has developed an innovative antibacterial hydrogel, exploiting the strong background in the synthesis and characterization of nanomaterials, both oxides and metals. The expertise of the group in the field of colloidal science has been fruitfully transferred to the control of surface chemistry of Nanoparticles (NPs) and of bulk surfaces, in order to produce functional materials (self-cleaning and flame retardant textiles, antibacterial and water repellent surfaces, catalysts for heterogeneous reactions) and to study the bio-interaction of NPs for nanosafety purposes.
The innovative technology is an effective antibacterial hydrogel, with tunable viscosity applicable on every kind of surface for producing antibacterial coating and achieved at room temperature by means of a totally green process. Thanks to this one pot preparation method spherical silver nanoparticles of about 15-20 nm are prepared in form of concentred hydrogel suspensions (0.5-1%wt) and stable over time (12 months). Compared to reference commercial silver NPs, the innovative hydrogel shows higher antimicrobial activity against several bacteria, as Escherichia coli strains and much lower cytotoxicity , furthermore an enhanced integration with cellulosic substrates.

The Italian researchers are looking for an industrial partner for manufacturing agreement. The partner should be interested in the development of large scale antibacterial products or surfaces using the patented synthesis on hydrogel.The group will offer its technical assistance for transferring on large scale the synthesis and application of the silver antibacterial active component.
Furthermore, the researchers are interested in research cooperation agreement to collaborate with other entities on the development of commercial products containing the innovative technology as antibacterial, to produce antibacterial surfaces or to develop new applications and products based on the technology.
