Microphotograph of nanofibre tag. (a) Epifluorescence image (excitation, 365 nm; magnification, ×10) of shadow-masked array of organic nanofibres. Distinct fibres are seen in the shadowed areas while non-shadowed consists of structureless film. (b) Blow-up (magnification, ×50) of a corner of the fibre-covered square, showing that individual fibres are grown underneath the masked area.
