Abstract: Macromolecular imprinted silica particles (“MIP”) in the presence of polymer grafted carbon black are disclosed. The disclosed molecular imprinted beads can detect disease in body fluids. For the silica gel matrix, tetraethyl orthosilicate (TEOS) was used as the backbone monomer and 3-aminopropy/triethoxysilane (APS) as a functional monomer. Carbon black was added to the sol-gel process, yielding black silica particles. Furthermore, sodium dodecyl sulfate (SDS) was used as a structure-directing agent to increase network diffusion of the template. A total of 16 MIPs were synthetized in parallel with variables that evaluate the role of key reactants in the synthesis procedure. Agglomeration tests were performed with all 16 MIPs in the presence of their template, alongside their respective controls using only phosphate buffered saline (“PBS”). Each of the MIPs was evaluated using a novel device capable of simultaneously measuring up to four samples for near infrared transmission.

Abstract: The present invention is based on the seminal discovery that targeted immunomodulatory antibodies and fusion proteins can counter act or reverse immune tolerance of cancer cells. Cancer cells are able to escape elimination by chemotherapeutic agents or tumor-targeted antibodies via specific immunosuppressive mechanisms in the tumor microenvironment and such ability of cancer cells is recognized as immune tolerance. Such immune suppressive mechanisms include immunosuppressive cytokines (for example, Transforming growth factor beta (TGF-?) and regulatory T cells and/or immunosuppressive myeloid dendritic cells (DCs). By counteracting tumor-induced immune tolerance, the present invention provides effective compositions and methods for cancer treatment, optional in combination with another existing cancer treatment.
