Which among the following are the ways in which a microfluidic membrane made from PDMS can be bonded to a glass substrate? UV adhesive curing Oxygen plasma activation and bonding Using transparent double-sided adhesive All of the above
Answers
Answer:
A microfluidic membrane made from PDMS can be bonded to a glass substrate by using the technique of Oxygen plasma activation.
There are some reports which have tried to adhere PDMS membranes to glass substrates using a UV adhesive curing technique and a transparent double-sided adhesive, they faced many issues like leaking.
Hence, till date, Oxygen plasma activation provides the best results.
Explanation:
Answer:
Oxygen plasma activation is a plasma treatment. Oxygen here is used to clean surfaces before bonding. All these systems work with oxygen gas. Plasma bonding is the process of creating a surface for bonding or printing.
This process modifies the surface and allows any material to bond to the surface. The plasma bonding technique enables to finish bonding of microfluidic membrane to glass substrate.
The process used for PDMS needs surface activation. For this, oxygen plasma activation is used mainly for bonding to glass. Oxygen is used to clean surface, hence the name oxygen plasma membrane.
