Abstract: A microfluidic chip device includes a substrate layer and a microfluidic layer. The substrate layer is made from a shape memory polymer, and includes a transformative portion that can change in volume when changing in shape between a memory shape and a temporary shape. The microfluidic layer is laminated with the substrate layer and has a microchannel that is in fluid communication with the transformative portion. The transformative portion produces a fluid driving pressure within the microchannel when changing between the memory shape and the temporary shape. A method of making the microfluidic chip device is also disclosed.

Abstract: A method for forming a molecularly imprinted polymer biosensor includes: (a) preparing a reaction solution including an imprinting molecule, a functional monomer, an initiator, and a crosslinking agent; (b) disposing the reaction solution in a space between upper and lower substrates each of which is made of a light-transmissible material; (c) disposing on the upper substrate a photomask having a patterned hole; (d) irradiating the reaction solution through the patterned hole of the photomask and the upper substrate so that the reaction solution undergoes polymerization to form a polymer between the upper and lower substrates; (e) removing the upper substrate after the polymer is formed on the lower substrate; and (f) extracting the imprinting molecule from the polymer so that a patterned molecularly imprinted polymer film is formed on the lower substrate.

Abstract: A micro actuator system includes a micro actuator and a light beam generator. The micro actuator includes a substrate, a cantilever beam, and a carbon nano-tube layer. The cantilever beam has a connection portion connected to the substrate, and the carbon nano-tube layer is disposed on the cantilever beam in a spray deposition technique. When the light beam generator generates a light beam for irradiating the carbon nano-tube layer on the connection portion of the cantilever beam, the carbon nano-tube layer drives the cantilever beam to be deformed towards a first direction.

Abstract: The invention discloses an anesthetic sensing optical microfluidic chip system. The anesthetic sensing optical microfluidic chip system includes a biochip, a light source, and a detector. The biochip includes a substrate, a micro-channel, and a molecularly imprinted biosensor. The micro-channel is bonded beyond the substrate. The molecularly imprinted biosensor is disposed in the micro-channel, and a surface of the molecularly imprinted biosensor has a plurality of imprinted sites. When a sample including a plurality of anesthetic molecules is injected into the micro-channel and flowing through the surface of the molecularly imprinted biosensor, some of the anesthetic molecules are captured by the imprinted sites. The light source emits a sensing light to the plastic biochip, and the detector receives the sensing light passing through the imprinted sites on the surface of the molecularly imprinted biosensor and generates a detecting result based on the received sensing light.

Abstract: A method of manufacturing a plastic surface with superhydrophobicity and high transparency is disclosed. In this method, a thermal nanoimprinting mold method is used to form a plurality of sub-20 nm nanograss structure on a surface of a cyclic-olefin copolymer (COC) material, so that the surface can have superhydrophobicity and high transparency at the same time.
