Case Studies

Nanoparticles (NP), defined as having one or more dimension of 1-100 nm, are used in a range of modern products, including cosmetics, sunscreen, coatings for solar cells, and materials for water treatment. A factor for their extensive use is the greater chemical activity imparted by their large surface area relative to their si...

Nanoparticles are becoming increasingly used in a wide range of areas, and thus are expected to soon have a significant economic and environmental impact. In health they are used for targeted drug delivery, and in the energy sector they are used in photovoltaic technologies to improve solar cell efficiency compared to conventio...

Magnetic Resonance Imaging (MRI) is a diagnostic, mainly qualitative, technique used to visualise the soft tissues of a patient. The application of a strong magnetic field causes the protons in a patient’s hydrogen atoms to align with it. Radiofrequency pulses are then used to force the protons to move out of and back into alig...

One in two people will develop cancer in their lifetime. Radiotherapy, using external sources of radiation, is a common treatment approach. This includes photon sources, such as x-rays and γ-rays, and particles, such as electrons, protons, and carbon ions. Radiation doses must be carefully calculated – too high a level and heal...

Extracellular vesicles (EVs) are biological nanoparticles actively released by cells, comprising of an outer lipid membrane, and containing markers indicative of the cell of origin, and housing an inner aqueous core. Most EVs are 100 nm in diameter or less but can range in size from 30 nm to a few micrometres. EVs are found in ...

Since 1938, when the first instrument for detecting alcohol in breath was developed, the ‘breathanalyser’ has become increasingly sophisticated. These instruments determine if a person has potentially consumed alcohol by measuring the concentration of ethanol in air exhaled from their lungs. They are now used by law enforcement...
