Preparation of Microfluidic Devices Using Micropatterning of a Photosensitive Material by a Maskless, Liquid‐Crystal‐Display Projection Method

An all-in-one device for fabricating microfluidic devices is developed by modifying a commercially available liquid-crystal-display projector. Micropatterns are formed on photosensitive materials from images that are prepared using personal-computer software. Desired poly(dimethylsiloxane) microfluidic channels (see Figure) are obtained rapidly without the need for expensive photomasks and light sources.
