Intra-body transmission networks are proposed to be composed of nanostructured or micro-sized detectors placed within the body to monitor health and distribute drugs. Transplanted biosensors are the potential options for monitoring the body for the detection of particular ailments and determining a diagnosis with the help of a doctor. Biological systems inside the body remain intricately integrated and interact primarily through biochemical interactions. Thus, the continuous communication performance and intrabody molecular nanonetworks coordinate essential functions within the human body. Spontaneous intrabody molecular nanonetworks, on the other hand, have yet to be investigated using sophisticated tools of information and communication concepts. We intend to understand the exquisite molecular networking that exists within us to design and develop pragmatic, effective interaction for evolving nanonetworks and also to lay the groundwork for the progression of groundbreaking diagnosis and therapeutic methodologies inspired by technological tools, which have the potential to be helpful in future nanotechnologies and bioinspired molecular communication (MC) applications.
