The silica crystal array can also be used for pulsed fields by adding two additional reservoirs to the PDMS cover to create a 120° crossed field. The mobility of different size long DNA (48.5, 23.1, and 9.4 kbp) vary in the pulsed-field array, indicating that they could be separated in such an array if a suitable injection system were employed. The high electric fields and rapid pulse times employed in these experiments are comparable to pulsed-field electrophoresis in the DNA prism pillar array [37]. [Pg.1521]

Separation and mixing of fluids are common operations in chemical and biological assays. When scaled down to microfluidics, these operations are usually achieved by micro pillar arrays. Figure 16 shows an electrochromatography pattern, formed by imprinting a COC... [Pg.2099]

Figure 4. (a) SEM pictures of a series of perpendicular pillar arrays whose wetting behavior is going to be compared with that of the taper-shaped structures, (b) The series of taper-shaped structures formed by the backside exposure conditions. Both pictures show structures created with a UV mask with square structure of 30 om width and distances from 30 om to 120 jm. [Pg.207]

Further, if the colloidal monolayer is heated above its glass-transition temperature, the colloidal monolayer will be deformed. Based on the 2-D heat-deformed colloidal monolayers, we presented a simple approach to prepare large-sized hexagonal nano-pillar arrays by solution-dipping method [30]. In this method, first, the... [Pg.315]
