A nanometre? That’s a billionth of a metre. A nanosecond? That’s a billionth of a second. Nanowatt? Billionth of a Watt. The list goes on, confounded only by that annoyance that is the kilogram, the SI unit of mass. A kilogram being a thousand grams, but a nanogram isn’t a ...
The performance of a micromanipulator can suffer from various mechanical issues, including drift, backlash, side play, and sticking. Understand these issues and how our engineers have implemented solid design principles to avoid potential movement issues from the start. ...
This science is based on nanotechnology, a field of innovation concerning the building of materials and devices at the atomic and nanoscale. To give you a sense of how minute this scale is, a nanometre is just one-billionth of a meter, also known as the billionth-scale. ...

The word virus comes from a Latin word describing poisonous liquids. This is because early forms of isolating and imaging microbes couldn't capture such tiny particles. Virus sizes vary from the extremely minuscule - 17 nanometre widePorcine Circovirus, for example - to monsters that challenge the...
The resolution of SEM is normally around 10 nanometres (nm). The maximum resolution for a scanning electron microscope image depends on factors such as the interaction volume of the beam and the electron spot size. SEMs can achieve a high resolution of below 1 nanometre (nm), although they...
