Guittard, F., Salapare III, H. S., Samitier, J., (2019). Selected Papers from N.I.C.E. 2018 Biomimetics MDPI

Nature has developed processes and robust materials, which possess superior physical, chemical, and electromagnetic properties that can withstand the most extreme conditions. We need to take inspiration from nature to obtain a more sustainable development. By combining our knowledge of processes and the knowledge of natural systems, we can create “biomimetic” solutions to the problems that we are facing as a consequence of the over-exploitation of our natural resources. Nice, France, the capital city of the French Riviera, once again welcomes the 4th edition of the International Conference on Bioinspired and Biobased Chemistry and Materials (“Nature Inspires Creativity Engineers” or N.I.C.E. 2018 Conference) from 14 to 17 of October, 2018. As in the previous editions, we are expecting hundreds of scientists and engineers to share the latest developments in the growing field of bioinspired and biobased chemistry and materials. It is a unique opportunity to understand the new challenges, to initiate new collaborations and to envisage sustainable solutions for the future.

Fernandez, Javier G., Samitier, Josep, Mills, Christopher A., (2011). Simultaneous biochemical and topographical patterning on curved surfaces using biocompatible sacrificial molds Journal of Biomedical Materials Research - Part A , 98A, (2), 229-234

A method for the simultaneous (bio)chemical and topographical patterning of enclosed structures in poly(dimethyl siloxane) (PDMS) is presented. The simultaneous chemical and topography transference uses a water-soluble chitosan sacrificial mold to impart a predefined pattern with micrometric accuracy to a PDMS replica. The method is compared to conventional soft-lithography techniques on planar surfaces. Its functionality is demonstrated by the transference of streptavidin directly to the surface of the three-dimensional PDMS structures as well as indirectly using streptavidin-loaded latex nanoparticles. The streptavidin immobilized on the PDMS is tested for bioactivity by coupling with fluorescently labeled biotin. This proves that the streptavidin is immobilized on the PDMS surface, not in the bulk of the polymer, and is therefore accessible for use as signaling/binding element in micro and bioengineering. The use of a biocompatible polymer and processes enables the technique to be used for the chemical patterning of tissue constructions.
