Surface molecular property modifications for poly(dimethylsiloxane) (PDMS) based microfluidic devices
Fast advancements of microfabrication processes in past two decades have reached to a fairly matured stage that we can manufacture a wide range of microfluidic devices. At present, the main challenge is the control of nanoscale properties on the surface of lab-on-a-chip to satisfy the need for biomedical applications. For example, poly(dimethylsiloxane) (PDMS) is a commonly used material for mi...
متن کاملSurface Micromachining of Polydimethylsiloxane (pdms) for Microfluidic Biomedical Applications
A major technical hurdle in microfluidics is the difficulty in achieving high fidelity lithographic patterning on polydimethylsiloxane (PDMS). Here, we report a simple yet highly precise and repeatable PDMS surface micromachining method using direct photolithography followed by reactive ion etching (RIE). Our method to achieve surface patterning of PDMS applied an O2 plasma treatment to PDMS to...
متن کاملModification of the glass surface property in PDMS-glass hybrid microfluidic devices.
This paper presents a simple method to change the hydrophilic nature of the glass surface in a poly(dimethylsiloxane) (PDMS)-glass hybrid microfluidic device to hydrophobic by an extra-heating step during the fabrication process. Glass substrates bonded to a native or oxygen plasma-treated PDMS chip having microchambers (12.5 mm diameter, 110 µm height) were heated at 200°C for 3 h, and then t...

متن کاملAdhesive-based bonding technique for PDMS microfluidic devices.
We present a simple and inexpensive technique for bonding PDMS microfluidic devices. The technique uses only adhesive tape and an oven; plasma bonders and cleanroom facilities are not required. It also produces channels that are immediately hydrophobic, allowing formation of aqueous-in-oil emulsions.
