A Perfect Day

Deirdre Kavanagh

This photograph shows a Y-shaped PDMS (polydimethylsiloxane, a type of polymer ) Microfluidic channel filled with green dye. The channel is 100 microns wide and leak-free. The channel walls are extremely smooth. The green colour and the shape of the channel reminding of the peace symbol, make me think that it was just “a perfect day”.
