Abstract:
Electronics and computational techniques are increasingly being used to analyze biological cells to diagnose diseases and develop methodologies to cure diseases inside the body. One such technology is ‘Nanotechnology’. The paper emphasizes on the best and effective utilization of Nanotechnology in the treatment of cancer. The design of nanodevice is based on the constant study of cancer cells and nanotechnology.
The nano device is injected to the patient which can travel through blood vessel, identify and destroy cancer cells. The system is fully automated whereby the device manages to move to the affected cells through certain algebraic calculations automatically wherever it might be placed. This would be loaded into a simple microprocessor like 8085 and can be embedded along with the nanodevice for automatic discovery of cancer cells. Manual guidance and monitoring is done to control the device explicitly, further more command signals are activated automatically or manually to destroy the affected cells through RF signals. The theme is based on the fact that the cancer cells get destroyed on exposure to RF signals, due to high heat generation.
In our paper we design a device that contains sensors, transceivers, motors and a
processor which are made up of biodegradable compound. No more destruction of healthy cells
due to harmful toxins and radiations generated through chemotherapy and radiation therapy.
INTRODUCTION
Electronics and computational techniques are increasingly being used to analyze biological cells to diagnose diseases, and develop methodologies to cure the diseases inside the human body.
The main aim of this paper deals with the eradication of cancer cells by providing a steady, possible method of destroying and curing the cancer in an efficient and safe way so that healthy cells are not affected in any manner. This technology also focuses on a main idea that the patient is not affected by cancer again. The purpose of using the RF signal is to save normal cells.
A Nano technology:
A nanometer is one billionth of a meter - 1/80,000 the width of a human hair, or about the combined diameter of ten hydrogen atoms. Nanotechnology is the art of manipulating materials on the atomic or molecular level and is used to build microscopic devices such as robots and other machines. These miniature devices play an important role in providing safe and efficient analysis and treatment of disease.
PROCESS
The initial step of identifying the cancer and the location can be done by scanning. Once the location has been identified through scanning, the task is to position the nanodevice to the exact location. We focus on the positioning of the nanodevice into the required location by itself. The nanodevice is allowed to be placed into any part of the body (or) the nano device is injected through the blood vessel. The positioning is done with the help of mathematical calculations. External Control signals could be used to avoid mishap or any other errors. The nanodevice is loaded with a microchip. The device is also provided with the compounds concealed so that it is initiated externally through a computer. The nano device contains sensors, motor, genereader, processor, transciever, camera and power supply. The location of the cancer cells is given as co-ordinates in a 3-dimensional point of view. This point is considered as the reference and referred as (0,0,0).
POSITIONING
The nanodevice performs an internal calculation based on the difference between its current position and the reference. Mathematical computations involve such that only one axis is compared between the nano device and the reference at a time. The motor fan is placed in a particular direction for a particular reference comparison. After one of the axis is completed and comparison is done, then the next axis is being compared followed by the third.Thus the three co-ordinate comparison of the nano-device results in any 3-dimensional orientation of the nano-device and results in exact positioning.
NAVIGATION
The output of the mathematical operation is given to a driver circuit (motor).The driver helps the device to navigate through the blood with precision in direction and with the required speed. The device thus should sample its new position with the reference at a sampling rate. The sampling rate is made such that their value is less than the velocity of blood flow.
The cancer killer could thus determine that it was located in (say) the big toe. If the objective was to kill a colon cancer, the cancer killer in the big toe would move to the colon and destroy the cancer cells. Very precise control over location of the cancer killer's activities could thus be achieved. The cancer killer could readily be reprogrammed to attack different targets using acoustic signals while it was in the body.
