Pascal Tomakidi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10259915
    Abstract: The present invention relates to substrates comprising a crosslinked network of covalently attached antimicrobial and/or antibiofouling polymers. The crosslinked network of antimicrobial and/or antibiofouling polymers acts highly efficiently against pathogens, e.g. bacteria and fungi. Both the antimicrobial and the antibiofouling cross-linked polymer networks are preferably better resistant to mechanical damage than simple surface-immobilized polymer monolayers. The antimicrobial and/or antibiofouling polymers of the crosslinked network are preferably obtained by ring opening metathesis polymerization (ROMP) and exhibit a molecular weight of preferably more than 30,000 or even 100,000 g mol?1. The crosslinked network of antimicrobial and/or antibiofouling polymers is preferably covalently attached to the surface of a substrate, e.g. an implant, a medical device, medical equipment or a (tissue-supporting) biomaterial, etc.

  • Patent number: 9937278
    Abstract: The present invention is directed to a biocompatible and preferably biodegradable gradient layer system comprising at least one set of layers comprising a biocompatible and preferably biodegradable cross-linked polymer and at least one biocompatible and preferably biodegradable support layer, wherein a gradient is preferably formed with respect to the mechanical and/or physical properties of one or more layers of the at least one set of layers comprising a biocompatible and biodegradable cross-linked polymer and/or the at least one biocompatible and preferably biodegradable support layer. The at least one support layer preferably comprises a biocompatible and preferably biodegradable meltable polymer and/or a biocompatible and incorporable material. This biocompatible and preferably biodegradable gradient layer system may be used as a biomaterial for regenerative medicine, particularly as a wound dressing or for tissue support.

  • Patent number: 9332755
    Abstract: The present invention relates to substrates comprising covalently attached antimicrobial polymers, which act as synthetic mimics of antimicrobial peptides (SMAMPs) and are preferably obtained by ring opening metathesis polymerization (ROMP). The inventive antimicrobial polymers exhibit a molecular weight of more than 100,000 g mol?1 and are preferably covalently attached to the surface of a substrate, e.g. an implant, a medical device, medical equipment or a (tissue-supporting) biomaterial, etc. Covalent bonding may be carried out using a photoreactive crosslinker but also by “grafting onto” or “grafting from”. The present invention is also directed to uses of the inventive antimicrobial polymers as defined herein, e.g. for antimicrobially coating a surface of such a substrate with a layer of the inventive antimicrobial polymer.

  • Patent number: 8980278
    Abstract: The present invention is directed to a bio-functionalized stimulus-responsive dissolvable PEG-hydrogel. This inventive stimulus-responsive dissolvable PEG-hydrogel comprises a matrix of PEG-polymers, which are modified to contain at least one multifunctional fusion protein, the multifunctional fusion protein preferably comprising as components a substrate binding peptide (SBP), preferably a repetitive RGD-binding peptide and/or a ZZ-binding domain, preferably a tag for purification, and at least one N- and/or C-terminal linker. The present invention is furthermore directed to the use of such inventive stimulus-responsive dissolvable PEG-hydrogels in the treatment of lesions, in surgical dressings, for wound treating, for soft and hard tissue regeneration, for the treatment of wounds in the oral cavity, in the field of ophthalmology, in the field of periodontal defects, etc. The invention also describes a method of treatment for such diseases.
