Nanomedicine is the medical application of nanotechnology. Specifically it is about manipulation and using the knowledge of molecules and atoms of the human body.
Ideally Nanomedicine aims to diagnose treat and prevent traumatic injury and diseases in the human body and to improve the health of a human being. Notably it has been known to fully change the medical science[1]. The sections of this paper seek to discuss the history and Concepts of Nanomedicine the current uses and lastly the possible future applications.
History
From the beginning nanomedicine has been an essential part of the nanotechnology. The physicist Richard Feynman was the first person to begin this the concept. Keenly to note this was from Caltech a time when he attended a meeting in American Physical Society where he spoke to them in December of 1959. The talk he gave is believed to be the first speech on engineering and technology at the atom scale ever. Notably this also acted as the constitutive force to a lay a foundation for nanomedicine as an essential part in science and medical treatments[2].
As a Nobel winner Richard P Feynman in his paper Theres Plenty of Room at the Bottom Feynman had given a nice description of a process where described scientists would gain the knowledge and be able to manipulate and control individual atoms and molecules based on a theoretical set of scales. And Although the term nano has appeared severally in it Feynman in his paper is labeled as the founding text of nanotechnology. The production and control of machines that are tiny using the quantum mechanics and foresaw that development of more sophisticated and more precise microscope s would open access to the area of single and individual atoms and arrangement of the atoms in the desired way would be possible and also if possible to overcome the scaling issues like gravity versus surface tension and Van der Waals attraction/repulsion. This laid a platform where the future scientist would start and grow from it[3].
This now was a new field of research that awakened other scientists who got interested and as a result they came up with two main directions of thought that seemed to describe the two main possibilities that would help to produce nanostructures. This two ways included the top-down and the bottom-up approach of the nanostructures. This ideology became very popular and it was the talk of the day in 1986 when the first discussed book of nanotechnology which had a lot of controversies a book called Engines of creation. The Coming Era of Nanotechnology was published by author Eric Drexler.
This author described in this book the ways to construct the complex machines from individual atoms and which would manipulate the molecules and atoms independently and as a result produce things and self-replicate. Also Eric Drexler suggested the notion of cell repair machines that became very popular and was deeply discussed in his controversial book. Some of the cells that would be repaired were damaged DNA organelles and other cellular structures with great precision. His book at that particular time was known to be visionary book and gave several possibilities in the area of nanotechnology
Eric Drexler is known to have grown upon Feynmans inspiration and continued to propose the basic ideas of a nanoscale assembler that would be very essential to be able to build a copy of itself and other items that would enable that capability of independent operation after its embryonic period.
