Impact of environmental changes on life and environmental health

Abstract Nanotechnology is an emerging multidisciplinary approach that recruits conventional methodologies integrated with advanced innovations in fields like health and diagnostics, electronics, the environment, and so on. To evaluate environmental risks and the pattern of disease pathogenesis, the new and promising field of nanoscience is a “key technology.” It can provide solutions in terms of quick diagnosis and treatment in healthcare by developing cheaper and quicker assessment methods using novel nanoproducts and processes. Novel nanodevices are expected to have a positive impact on human health as well as the environment. In addition, the nanotechnologies in medicine and physiology as well as for evaluating environmental risks efficiently predict nano-level interactions with the subcellular/molecular levels of the body and show a high degree of sensitivity and specificity in understanding targeted drug delivery mechanisms and various risk evaluation analyses. The technology, however, lacks in terms of evidence from advanced clinical trials and scaled-up commercialization to ensure safety and stability. Thus, there is a need for specific studies based on target cells or tissue specificity to increase therapeutic efficacy and safety for more efficient clinical applications, keeping in view the related moral and ethical issues in terms of health security and environmental safety.
