The Question of Ethics in Nanomedicine

Abstract

Lately, nanotechnology and nanomedicine have achieved tremendous interest and funding, from several entities and directions. Nanomedicine demonstrates great promise for development of medical diagnosis, treatment, and prevention; it also raises various ethical concerns however, there has not been so much study and discussion about social and ethical issues. Nanomaterials are extremely reactive in biological systems owing to the large surface area. Although the benefits of nanomaterials are apparent, there are some studies which show the potential risk to biological systems. Therefore, the rapid progress of nanomedicine and its potentially profound social and environmental impacts is indicative of how the arisen problems could be dangerous and already there are signs that some challenging ethical issues could be raised. In this paper we will examine more recent developments in debates on nanomedicine ethics.

An Updated Review on the Application of Dendrimers as Successful Nanocarriers for Brain Delivery of Therapeutic Moieties

“…• The BBB Endothelial cells are characterized by increased mitochondrial content, minimal pinocytotic activity, and lack of fenestrations [13]. The restricted paracellular permeability of the capillary endothelial cell is attributed to the two intercellular molecular binding systems-the junction and the tight junction [14].…”
