The use of nanotechnology in cancer treatment offers some exciting possibilities, including the possibility of destroying cancer tumors with minimal damage to healthy tissue and organs, as well as the detection and elimination of cancer cells before they form tumors. Over the past decade, together with the improvement of traditional cancer treatments, conveniently designed (with respect to their size, shape, main material, and coating) and specifically targeted nanovehicles have been developed. Nano-sized carriers can be functionalized to recognize key structures expressed in cancer cells and/or their surrounding tissues. Recently, some more complex systems have been developed that exploit the human body's own communication systems to enhance their efficacy. Some of the newest nanoparticles have the capacity to not only serve as drug delivery systems for myriad molecules, but also operate as direct cancer treatment agents themselves, such as in thermal therapies.
Journal impact factor is an index or a criteria devised by Eugene Garfield to categorize journals based on their citations. Impact factor is considered as a putative marker to indicate the journal quality. But the recent policies being adopted to improve the impact factor is becoming a topic of controversies today. This current scenario questions the reliability of impact factor. The citation index cannot be considered to determine the scientific quality of an article because the technicalities are not considering the scientific quality. Knowing or reading an article is not enough to determine their quality validating the content and approving the findings and revalidating the facts is vital in scientific research. It is highly impossible to do a scholar check in each and every article to detect fraudulent or unsubstantial citations.
