Microchannels fabrication

This chapter illustrates basic concepts, instrumental aspects, and modes of separation of electromigration techniques performed in capillary format. It shonld be noted that most of the fundamental and practical aspects of the electromigration techniqnes performed in capillary tubes also apply when the techniques are carried out in microchannels fabricated on plates of reduced dimensions, communally referred to as chips. [Pg.157]

Henares et al. [210] developed a multiple enzyme linked immunosorbent assay (ELISA) chip by using capillary-assembled microchip (CAs-CHIP), which involved simple embedding of a 2 to 3 mm length of square capillaries possessing valving and immunoreaction functions into the microchannels fabricated on a PDMS substrate. The authors immobilized different anti-IgGs... [Pg.232]

Yen et al. [9] (University of Califomia/Pennsylvania State University) presented a bipolar Si-based micro-DMFC with an integrated MEA (Nafion -112 membrane) and 750 im wide and 400 pm deep microchannels fabricated using Si micro-machining (DRIE). This pDMFC with an active area of 1.625 cm has been characterised at near room temperature (RT), showing a maximum power density of 47.2 mW cm at 60°C when 1 M methanol was fed but only 14.3 mW cm at RT. Since then, Lu et al. [10] have enhanced the performance of the pDMFC to a maximum power density of 16 mW cm at RT and 50 mW cm at 60°C with 2 M and 4 M methanol supply with a modified anode backing structure enabling to reduce methanol crossover. [Pg.126]

Uniquely, Minagawa et al. demonstrated the integration of two chemical processes on a chip a chelating reaction and solvent extraction. The layout of the microchannels fabricated on the glass plates is shown in Figure 35.4 and a schematic illustration of the molecular behavior demonstrated... [Pg.1023]

The toner material and the direct-printing approach may not only be used for PT microchannel fabrication but also to produce a great variety of features, devices, or elements for analytical microsystems. For example, other essential elements for electrophoresis microchips are the... [Pg.1175]

Variation of overcut during microdriiiing and microchannel fabrication. [Pg.133]

Given the different types of materials (glass, silicon, poly(dihydroxymethyl silicate) (PDMS), different types of other polymers) used in microchannel fabrication, various techniques have been adopted to achieve the goal mentioned above. Three broad types of filters are seen frequently ... [Pg.1847]
