Patents by Inventor Constantinos Paleos

Constantinos Paleos 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: 7767091
    Abstract: The invention deals with lipophilic modified dendrimers and hyperbranched polymers that can encapsulate organic pollutants of a diversity of sizes and shapes and which are prepared following the modification of the functional groups present at the surface of the polymer. These functional polymers are characterized by the fact that their nanocavities do not have predetermined dimensions but their size and shape are affected by the size and shape of the pollutant they will encapsulate or otherwise they will be so-adjusted to it.
    Type: Grant
    Filed: January 21, 2004
    Date of Patent: August 3, 2010
    Assignee: The National Center for Scientific Research “Demokritos”
    Inventors: Constantinos Paleos, Dimitrios Triourvas, Oreozili Sideratou, Michael Arkas
  • Publication number: 20060204472
    Abstract: The present invention deals with the synthesis of multifunctional dendrimeric and hyperbranched polymers for application as drug delivery systems of bioactive pharmaceutical compounds and as gene delivery systems (carriers of genetic material), the latter through condensation with genetic material. Specifically, the present invention deals with the synthesis of multifunctional compounds based on appropriate dendrimeric or hyperbranched polymers at the terminal surface of which have been introduced functional groups X, Y, Z. In addition, for gene delivery to cells these multifunctional systems will become cationic for the formation of complexes with negatively charged genetic material. The functional groups render the delivery systems recognizable by complementary cell receptors. Furthermore they render the systems stable in the biological milieu and facilitate their transport through cell membranes.
