We are also involved in UK NERC-funded projects as well as other national and international initiatives. We coordinate or participate in a number of EU (FP7 and Horizon2020) funded projects including: NanoMILE, FutureNanoNeeds, NanoFASE, EcofriendlyNano, NanoDefine, QNano, NanoValid and MARINA. Scientists at Birmingham are international leaders in the field of nanotoxicology and play a leading role in the translation of scientific advances towards the regulation of nano-enabled products. A new research area, nano(eco)toxicology, has emerged in recent years, aiming to elucidate the toxicity potential of nanomaterials, linked to their physico-chemical characteristics and their interactions with, and bioavailability to, organisms. In addition to all the potential applications of nanomaterials in the environment, it is possible that the novel physicochemical properties of nanomaterials described above may also lead to toxicity developing in novel or unexpected ways. These properties can be exploited for all sorts of applications such as environmental remediation, sensing and controlled delivery or capture of pesticides and other high value chemicals. Furthermore, due to their very small size, the surface area of nanomaterials is exceptionally high, a feature that also alters their properties enormously, and leads to high reactivity, and a large area for binding of biomolecules and other environmental entities. In simple terms, within the nanoscale materials can behave in novel and unexpected ways. At this length scale, material properties can be dominated by size-dependent features, such as quantum confinement and surface plasmon resonance. Nanoscience is the science at the nanoscale, where ‘nano’ refers to processes that occur on the size range between 1 and 100 nm. ![]()
