Abstract
The present invention provides a novel approach to cancer therapy and diagnostics that utilizes nanotubes and other similar nanostructures as both an indirect source of radiation therapy (BNCT), and as delivery vehicles for other types of radio- and chemo-therapeutic materials, as well as imaging agents for diagnostic purposes.
Claims13
A method for treating cancer, said method comprising:
- a) attaching a first antibody species to nanovessels to form a nanovessel-antibody composite species;
- b) introducing said nanovessel-antibody composite species into a mammal such that said nanovessel-antibody composite species selectively targets at least one type of cancerous cell;
- and
- c) exploding said nanovessels using at least one frequency of ultrasonic waves;
- wherein said at least one frequency of ultrasonic waves is adjusted to be absorbed by said nanovessels;
- d) attaching a second antibody species to BN nanostructures to form a BN nanostructure-antibody composite species, wherein said first antibody species and said second antibody species are selected from the group consisting of the same antibody species, different antibody species, and combinations thereof;
- e) administering said BN nano structure-antibody composite species to said mammal such that said BN nanostructure-antibody composite species selectively targets at least one tumor within said mammal;
- and
- f) activating at least some of the boron atoms in said BN nanostructure-antibody composite species.

- e) attaching a second IgG species to said at least one radioactive-laden carbon nanotube to form a radioactive-laden carbon nanotube-IgG species;
- f) introducing said radioactive-laden carbon nanotube-IgG species into said mammal;
- g) attaching a third IgG species to at least one nanovessel to form a nanovessel-IgG composite species;
- h) introducing said nanovessel-IgG composite species into said mammal such that said nanovessel-IgG composite species selectively targets at least one type of cancerous cell;
- and
- i) exploding said at least one nanovessel using at least one frequency of ultrasonic waves.
