This paper reports a design and fabrication of a functional nano robot “Sootha Vennai Parpamcutâvanai – Parpam – SVP” of 150-200 nm size which behaves more or less like a human physician in nano form inside the body. This nanorobot is a medicine which has artificial intelligence i.e. the distinguishing ability, decision making ability and some basic behavioral properties such as target detection ability, self-propelling capability and handling the infection in the case of breast cancer. This nanorobot can also aid in cancer therapy, site-specific or target drug delivery, and tissue repair.
