Application Of Nanotechnology In Healthcare

Seminar on Nanotechnology In Healthcare-slide presentation and report

Nanotechnology has the potential to make a significant impact on healthcare by delivering step-changes in disease diagnosis and monitoring, implants and regenerative medicine, drug delivery, as well as research tools for drug discovery and biomedical science.Exploiting the different and enhanced properties that nanoscale materials exhibit due for example to increased relative surface area, the emergence of quantum effects and nanoscale interactions with biological systems – presents challenges and opportunities for scientists, engineers and wider society.The very properties that make nanomaterials so exciting, such as increased reactivity and the potential to cross cell membranes, may also have negative environment, health and safety (EHS) impacts.

In addition, advances in healthcare technologies may also change social relationships in ways that pose ethical issues. For instance, technologies can change the relationship between patient and doctor issues, redefining the distinction between experts and patients. They can also precipitate more complex changes: from which diseases are prioritised and who gains access to treatments; to transforming our understanding of what it is to be human, through the use of novel technologies for enhancement.For nanotechnologies to make a positive impact on our lives, as well as funding the best science, setting research priorities also entails having to consider this wider context - to reflect on different potential outcomes for society.This project was developed to enable the Engineering and Physical Sciences Research Council (EPSRC) to take account of a wide set of societal views and inform nanotechnology research trajectories for healthcare - creating a space

through which citizens, scientists and stakeholders can engage in an informed debate on the public value, ethics and applications at an early stage.Specifically, it forms part of a range of consultation activities providing intelligence to inform the EPSRC in developing a Grand Challenge call for proposals under the cross Research Council programme Nanoscience through Engineering to Application. This is for large-scale, integrated research projects to exploit nanotechnology in the healthcare domain.

In the near term, the most important clinical applications of nanotechnology are likely to be in pharmaceutical

development. There are already an astonishing number of emerging applications.These applications either take advantage of the unique properties of nanoparticles as drugs or components of drugs per se or are designed for new  approaches to controlled release, drug targeting, and salvage of drugs with low bioavailability. For example, nanoscale polymer capsules can be designed to break down and release

drugs at controlled rates and to allow differential release in certain environments, such as an acid milieu, to promote uptake in tumors versus normal tissues. Substantial research is now designed for creating novel polymers and exploring specific drug-polymer combinations.
