Читать книгу Nanobiotechnology in Diagnosis, Drug Delivery and Treatment - Группа авторов - Страница 42

Nanotechnology is a novel and emerging technology having enormous applications in the whole biomedical sector, particularly in diagnosis, drug delivery, and treatment of a wide range of diseases such as infectious diseases, neurological disorders, cardiovascular diseases, cancers, etc. Therefore, considering the huge potential of nanotechnology in these fields it is believed that nanotechnology will play a crucial role in revolutionizing the current scenario of biomedicine (diagnostic and therapeutic strategies) and start a new era of nanomedicine. Nanomaterials have attracted huge attention in their use for diagnosis and management of varied diseases due to their novel and unique properties such as small size, high drug loading capacity, and biodegradable and nontoxic nature. In addition, nanomaterials also help to enhance the solubility of non‐soluble drug molecules, increase their bioavailability, and reduce the side effects caused by synthetic drugs.

Although nanotechnology in general, and nanomaterials in particular, have great potential in various avenues related to biomedicine, in some cases the cost factor becomes a hindrance in its use. Moreover, certain nanoscale materials lack long‐term safety data, therefore such issues need to be addressed. Apart from these challenges, nanomaterials and their approval methods have not been well defined until now, which brings another limitation and takes even more time in developing clinically useful nanotechnology‐based drug delivery systems and therapies.
