At the picture can be seen many Carbon nanotubes (CNT) dispersed all over the area. However, what catches the attention most, are the two CNT that are intertwined creating a straight line of more than 5µm

PLGA (poly lactic-co-glycolic acid) is a biodegradable and biocompatible copolymer that is widely used in the pharmaceutical industry as a drug delivery vehicle.PLGA microspheres were attached to a SEM stub with a carbon adhesive disc and being transferred using a squirrel hair brush. Excess sample was removed with a gentle spray of compressed air and then placed into the FEI Quanta FEG 200 for imaging. To enhance surface morphology of the spheres, a low accelerating voltage of 2KV was selected to be the optimum for this kind of sample with a chamber pressure of 180 Pascal’s. A digital image was captured, imported into photoshop and coloured by Steve Gschmeissner.
