“…Although several polymers including Parylene [24], Teflon [25], or polyimide [26] are relatively chemically inert and used in microchip materials, they still have high permeability as compared to glass, or are not optically transparent. Recently, glass coating methods with PDMS microchannels were developed in order to generate chemical stability [27], but these methods are difficult to apply to actuating parts.…”

Lab-on-a-chip technology is promising for the miniaturization of chemistry, biochemistry, and/or biology researchers looking to exploit the advantages of a microspace. To manipulate fluid on a microchip, on-chip pumps are indispensable. To date, there have been several types of on-chip pumps including pneumatic, electroactive, and magnetically driven. However these pumps introduce polymers, metals, and/or silicon to the microchip, and these materials have several disadvantages, including chemical or physical instability, or an inherent optical detection limit. To overcome/avoid these issues, glass has been one of the most commonly utilized materials for the production of multi-purpose integrated chemical systems. However, glass is very rigid, and it is difficult to incorporate pumps onto glass microchips. This paper reports the use of a very flexible, ultra-thin glass sheet (minimum thickness of a few micrometers) to realize a pump installed on an entirely glass-based microchip. The pump is a peristaltic-type, composed of four serial valves sealing a cavity with two penetrate holes using ultra-thin glass sheet. By this pump, an on-chip circulating flow was demonstrated by directly observing fluid flow, visualized via polystyrene tracking particles. The flow rate was proportional to the pumping frequency, with a maximum flow rate of approximately 0.80 μL/min. This on-chip pump could likely be utilized in a wide range of applications which require the stability of a glass microchip.

“…This geometry allows the defining of a quadrupolar electric field in the trap. The trapping efficiency and resolution are dependent upon the trap size (r 0 ) and trap depth (D z ) (Dziuban, Mroz et al 2004), and the operating voltage and frequency. Since its introduction by Paul to the early 1960s the quadrupole ion trap (QIT) was widely used as an ion storage device for mass spectrometric applications and radio frequency spectroscopy.…”
