Abstract: The present invention provides a generic platform for delivering molecules with low blood-brain barrier (BBB) penetration into the brain. The nano-delivery system is based on a core nanoparticle which is conjugated through a first polymeric linker to a brain-internalizing transporter moiety, and is further conjugated to a second polymeric linker bound to an active agent selected rom a biologically active molecule or a labeling molecule. Further provided is a process for preparation of the nano-delivery system. The present invention further provides pharmaceutical compositions comprising the nano-delivery system and its use in therapeutic and/or diagnostic methods.

Abstract: A nanoparticle having a lipidic core, wherein the nanoparticle is linked via first polymeric linkers to a glucose molecules, and is further linked via second polymeric linkers to chelating agents, and wherein a weight ratio of the chelating agents to the nanoparticle is 1:20 to 1:80, respectively, is disclosed. Uses of the nanoparticle, particularly for imaging a tumor in a mammal, are further disclosed.

Abstract: A method of detecting cancer cells is disclosed. The method comprises (a) contacting the cell which is suspicious of a cancerous or undifferentiated phenotype with 4-aminophenyl phosphate (p-APP) under conditions wherein alkaline phosphatase of the cell catalyzes a reaction of the cell with the p-APP, so as to generate a product capable of producing an electrical signal; and (b) measuring a level of the electrical signal, wherein a difference in a level of the electrical signal compared to a predetermined threshold is indicative of a cancer cell.

Abstract: A method of detecting cancer cells is disclosed. The method comprises (a) contacting the cell with a substrate for an enzyme under conditions wherein the enzyme catalyzes a reaction of the cell with the substrate, so as to generate a product capable of producing an electrical signal; and (b) measuring a level of the electrical signal, wherein a difference in a level of the electrical signal compared to a predetermined threshold is indicative of a cancer cell. The method may be adapted for diagnosis, monitoring a cancer therapy, identifying agents capable of treating cancer and individually optimizing a cancer therapy.
