A low-cost method of fabricating Parylene-SU-8 micro-nanofluidic chip by thermal nanoimprint and multilayer compositing
A new fabrication of micro-nano fluidic chips by thermal nanoimprint and multilayer compositing is proposed. The nano-channels with different aspect ratios were first manufactured by thermal nanoimprinting and Parylene layer coating, and the effect of parylene layer thickness on aspect ratio is studied. Then SU-8 layers with the micro channels and liquid reservoirs were superposed by ultraviolet exposure and secondary bonding to form a multilayer micro-nano fluidic chip. By optimizing the bonding parameters, a Parylene-SU-8 micro-nano fluidic chip with 200 μm wide and 8 μm deep micro-channels, cross-linked with 78 nm wide and 288 nm deep nano-channels was constructed, of which the maximum bonding strength is 0.92 MPa. This method has the advantages of simple process and low cost, which is suitable for mass manufacturing of micro-nano fluidic chips.
期刊介绍：
Microfluidics and Nanofluidics is an international peer-reviewed journal that aims to publish papers in all aspects of microfluidics, nanofluidics and lab-on-a-chip science and technology. The objectives of the journal are to (1) provide an overview of the current state of the research and development in microfluidics, nanofluidics and lab-on-a-chip devices, (2) improve the fundamental understanding of microfluidic and nanofluidic phenomena, and (3) discuss applications of microfluidics, nanofluidics and lab-on-a-chip devices. Topics covered in this journal include:
1.000 Fundamental principles of micro- and nanoscale phenomena like,
flow, mass transport and reactions
3.000 Theoretical models and numerical simulation with experimental and/or analytical proof
4.000 Novel measurement & characterization technologies
5.000 Devices (actuators and sensors)
6.000 New unit-operations for dedicated microfluidic platforms
7.000 Lab-on-a-Chip applications
8.000 Microfabrication technologies and materials
Please note, Microfluidics and Nanofluidics does not publish manuscripts studying pure microscale heat transfer since there are many journals that cover this field of research (Journal of Heat Transfer, Journal of Heat and Mass Transfer, Journal of Heat and Fluid Flow, etc.).
