dc.description.abstract | In chemical and biological assays, the synchronized control of multiple valves is very important. Currently there is no control scheme for the use of a large number of valves without adopting bulky peripheral control devices such as pumps or electrical equipment. Therefore, we propose a simple pH-responsive microvalve array system and a new multiplexing technology that, through its reliance on multiphase laminar flow, facilitates the operation of arrayed multiple microvalves. For the fabrication of the microvalve arrays, we have used pH-responsive hydrogel microspheres produced by a microfluidic chip. By incorporating these microspheres inside an arrayed microvalve polydimethylsiloxane (PDMS) platform, we produced pH-responsive arrayed microvalves with 'open' and 'close' operations carried out by the multiphase laminar streams of pH solutions. The constructed arrayed microvalves were adequately controlled by the multiphase pH buffer; the pressure of the pH-buffer solutions controlled the widths of the sample flow. Based on the simplicity and reliability of the operating principles, this new arrayed-valve system will decrease the need for complicated peripheral lines and will remove the need for many solenoid valves, which are currently used for the individual control of arrayed valves. | - |
