“…hot-embossing [11], injection, laser ablation [12,13], photolithography with moulding and milling. Another advantage is also a wide range of available polymers such as: poly(carbonate) PC, poly(methyl methacrylate) PMMA [14,15,16,17,18,19], poly(dimethylsiloxane) PDMS [20,21,22]. Polymers used must be appropriately selected, for example due to the mechanical properties and possible way of treatment.…”
