Introduction
    The implementation of nanotechnology has brought about a significant revolution in all the various fields ranging from medicine and healthcare, various technology and industry sectors, which are inclusive of information technology, homeland security, transportation, energy, food safety, environmental science, and so on. In the field of healthcare and medicine, nanotechnology has improved various sectors and processes, thereby revolutionizing the course and structure of the medical and healthcare field. It has helped in the process of broadening the medical tools, knowledge as well as therapies that are currently available to the clinicians of this era. Through the use of nanotechnology, medical practitioners are capable of providing precise solutions to various serious diseases and offer different cures, treatment, disease prevention, and early diagnosis. The medical field has experienced a huge amount of progress with the use and application of nanotechnology. As a result of its implementation, patient care has improved immensely.
Manipulating DNA
    Treatment of diseases has become a difficult feat due to the increasing number of complications arising in the human body. According to Keskinbora and Jameel (2018), treatment for specific diseases also involves a multitude of medications and separate treatments which become extremely hectic to follow as well as to maintain. In a world, where people are suffering from endless diseases, keeping up with regular treatments and checkups for multiple diseases and ailments has become an extremely difficult task. It is in this regard, according to Siemer et al. (2020), that treating diseases from their very sources or their points of origin has become an intrinsic part of medical science. Through the process of DNA manipulation using nanotechnology, these processes can be undertaken for the purpose of benefit of patients suffering from serious ailments. Therapies that are deeply involved with the manipulation of individual genes or even the molecular pathways that have an impact on their expression are used intensively in order to treat diseases.
    Various investigations regarding the use and implementation of nanotechnology in the field of medicine for the purpose of treatment of diseases are being conducted so as to accelerate the scope and capabilities of medical science in a comprehensive manner. According to Mostafavi, Soltantabar, and Webster (2019), the central aim of using nanotechnology in the arena of medical science is to tailor treatments that are individualistic in nature based on the genetic makeup of different patients. Scientists are currently working on a certain aspect of nanotechnology, which is called 'nano walkers'. The nano walkers are being used for the purpose of the creation of a biochip computer. It is attempting to investigate the process by which biological molecules crystalize. This is a specific area of the arena of medical science that is currently under a multitude of challenges. This is an essential part of biomimetics, which can be described by Li, Hu, and Cheng (2018), as the process by which nanotechnology will be capable of imitating several biological processes in nature, such as for instance, the behaviour of DNA as well as the technique of introducing new processes and improving the same.
    Various diseases can be treated at the very outset with the help of nanotechnology. The pace of treatment can increase to a great extent by using nanobots for the purpose of gene manipulation. For instance, according to Groner, Göpferich and Breunig (2021), nanotechnology is being used by a number of scientists for the purpose of both diagnosis and treatment of atherosclerosis, which can be described as the process by which plaque is built up in the arteries. In treating this particular disease, according to Li, Liang, Xiao and Qian (2018), the scientists and researchers have created a nanoparticle that functions by mimicking the ‘good’ cholesterol of the body, which is known as HDL or high density lipoprotein. Through this process, the buildup of plaque is effectively reduced and maintained at a lower level so as to prevent the occurrence of atherosclerosis. Through the process of treating atherosclerosis from its very source of the build up of plaque in the arteries, a lot of damages to the body can be effectively reduced as well as prevented.
    The researchers of nanotechnology are intensely researching about the various ways in which a nanoparticle can be used for the purpose of specific treatment of various serious ailments. According to Adir et al. (2020), the researchers are making their best attempts to treat the diseased cells of the body in a direct manner, instead of harming a cluster of cells. This kind of treatment of diseases through the help of genetic manipulation taking the help of nanotechnology is coming to aid for patients suffering from terminal diseases such as cancer. Using the upgraded information and support of nanotechnology, the researchers are using nanoparticles which are in a way, encapsulating the medication or helping the delivery of the same in some manner. Through this process, according to Zhang, Li, Gao, Chen and Liu (2019), with the help of the nanoparticles the medication is reaching directly to the infected cells. As a result of this, no harm is caused to the other healthy cells surrounding the same area. This has become one of the most effective as well as potential ways of treating deadly diseases such as cancer. It has also effectively reduced the negative and toxic impacts of chemotherapy on the healthy cells of the body.
