In 2000, Onikura et al. presented ultrasonic vibration grinding as a new way to fabricate USM mills. With a grinding wheel mounted on an axis, they could manufacture different tool geometries and produce specific tools for drilling, grooving, and free-form cutting and proof the capabihty of the micro drilling tools with 10-20 pm in diameter (Onikura et al. 2000,2004).

A third strategy for microfluidic-nanospray interfaces, microfahricated, tapered electrospray tips [8-12] is the most promising that has been reported. In fact, several devices with this configuration are now available commercially (for example, from Advion Biosciences and Agilent Laboratories). Several authors have fabricated devices capable of sustaining a stable spray with no dead volume between the channel and tip. For example. Fig. 2a shows a micro-milled electrospray nozzle in poly(methyl... 

This device is a generically simple reactor comprising a micro-channel Y-piece section and an elongated reaction micro channel attached [26, 27]. The microstructures were mechanically fabricated in PMMA using a flat end mill. A top plate was joined with the microstructured plate by baking under vacuum. The reaction temperature was fixed using a hot-plate. 

The micro chamber was fabricated using a milling machine [23],... 

Ultra-small micro end nulls (USM mills) are defined by a diameter smaller than 50 pm. They are often used to cut ductile materials for struc-mres with small radii, undercuts, and tool diameter determined geometries when the accessibility for machining is diameter dependent (Fig. 1). For example, they are used to fabricate medical instruments, micro valves, and so on (Masuzawa 2000 Onikura et al. 2004).

This is a fabrication procedure used to machine or modify materials on the micro-scale. A focused beam of high-energy ions is targeted at a material and the impacting ions sputter atoms from the surface a prescribed scanning of the ion beam thus has the effect of a milling procedure.
