Novel bio-based active release materials for biomedical applications
Tina Modjinou, Valérie Langlois and Estelle Renard
University of Paris-Est, France
With the increasing scarcity of oil resources and in a period of energy transition due to global warming and the impacts on
the biosphere, researches are conducted to find an alternative to petrochemical products. Among these resources, plants
have a growing interest since they are an enormous source of complex chemical molecules exploited in different fields such
as fragrance, food, cosmetic and pharmaceutical industries. Essential oils, present in plant resources, constitute a non-food
valorization of the biomass. The powerful and green process of thiol-ene addition was used to elaborate bio-based networks
from eugenol loaded with two phenolic compounds as active release materials. Carvacrol, a phenolic monoterpenoids present
in thyme or oregano, and tannic acid, a polyphenol family tannins (glucose polyester) known for their antibacterial and
antioxidant activities have been embedded in the cross-linked eugenol based network to increase its antibacterial properties.
Their antibacterial and antioxidant activities have been evaluated and promising properties have been demonstrated since
derived materials led to a tremendous inhibition of the adhesion of Staphylococcus aureus and Escherichia coli. Systems
proceeding by diffusion (carvacrol) or by diffusion and immobilization (tannic acid) of antibacterial and antioxidant moieties
have been obtained. Moreover, in the case of tannic acid, thematerials present the advantage of having a sustainable antibacterial
and antioxidant activities over time since an oxidative coupling reaction between phenol groups leads to the trapping of tannic
acid in the network.
Biography
Tina Modjinou has done her graduate studies (PhD) from East Paris Institute of Chemistry and Materials Science, France (Université Paris Est, CNRS) under
the supervision of Professor Estelle Renard. Her PhD work focused on the chemical modification strategies for biodegradable/biocompatible co-polyester mainly
PHAs for medical applications. The main goal of her studies is devoted to the design of new bio-based materials with antioxidant and antibacterial activities and the
improvement of theirs properties. She has published 3 papers in these research fields.
