<p>Membrane microfilters are formed in situ in a defined region of a blank (c) by embossing one surface of the defined region (e) of the blank (c) to provide an array of indentations (h), and ablating the material of the blank in the defined region until the indentations become through pores (p). Ablation may be carried out by various means such as chemical etching or laser ablation.</p> |
