ImageJ is amazing

Transect

A long time ago in a lab about 20 miles away, I was working for a company called Mediwatch to develop a new micro-array platform that was internally named Zero-flow. It was a nifty little device that was excellent at controlling the flow of a sample over a sensor system. The company I worked for at the time was small and not flush with cash. So for a while the only resources allocated to the design and development of this technology was me. With this budget of £0 I needed to produce an assay system that could demonstrate sensitivity significant Continue reading

Artistically linked research

Not a Hedgehog

Last week I read an excellent blog post by Johanna Kieniewicz on PLOS.org about the combination of art and science. The post details why blending art and science is important and how it can be highly productive for both groups. I am not very artistic (as my previous drawings demonstrate) but I enjoy exploring some of the more aesthetically pleasing areas of my work. Before coming to Cranfield I worked briefly as a consultant for an artist and it was very enlightening look at differing perspectives on the products of science. Reading the article at PLOS not only reminded me of Continue reading

Brewster angle Lego microscope

Lego BAM

Brewster’s angle is the angle at which light of a certain polarisation won’t reflect off a surface. The resulting reflection will then be made up of only light from a single polarisation (p-polarised). This little optical quirk is how polarised lenses remove lots of scattered reflections in photographs and why polarised sunglasses are so much better when lounging by the seaside. However, rather than just being something that makes sunny days even better, it also provides a neat trick for visualising things that would otherwise be invisible to other analytical methods. Brewster’s angle for water is approximately 53.1°, which is calculated Continue reading

Paper published in Thin Solid Films

A comparison of a calix[4]resorcinarene monolayer with (bottom) and without (top) surfactant

The latest output from the collaboration between us physicists and those chemist in Cranfield Health has appeared in print in the journal Thin Solid Films. The best bits of the paper are summarised below. Calixarenes are bucket-like molecules that have been put to use in a number of approaches in sensors. By altering the active groups that are presented in  the calixarene, they can be made specific to certain agents.  The molecules have been proposed for applications ranging from uranium recovery, thorough VOC sensing to ion-selective sensing. This paper explores the properties of a number of calix-4-resorcinarenes along with their Continue reading
