Spin coating machine working principle

The spin coating apparatus of the homogenizer is widely used in MEMS micro-fabrication, biology, material, and so on. It's used to prepare thin films with thickness less than 10 nm and is also commonly used in about 1-100 micron thick photoresist photolithography process. Many flat substrate materials are used for coating, such as semiconductor silicon [...]

Notes for pipette use

1.Pipette (pipette) should not be dried in the oven. 2. Pipette (pipette) shall not remove solutions that are too hot or too cold. 3. One pipette should be used repeatedly in the same experiment as far as possible. 4. After the pipette raises the liquid level, the liquid adhering to the external wall of the [...]

How to successfully complete PDMS and glass plasma bonding

1.Glass/PDMS plasma bonding Plasma bonding can be used in the fabrication of microfluidic chips. To permanently glue PDMS chips to the glass, the researchers used a plasma cleaner to change the surface properties of the glass and PDMS. The plasma treatment will change the surface chemistry and allow the PDMS to adhere to channels on [...]

ChIP-seq Technology

Sequencing after chromatin immunoprecipitation (ChIP seq) is a genome-wide analysis technique for DNA binding proteins, histone modifications, or nucleosomes. Due to the significant advancement of second-generation sequencing technology, ChIP-seq has higher resolution, lower noise, and more extensive coverage than its original version, ChIP-chip. As a result, ChIP-seq has become an indispensable tool for studying gene [...]

The role of PDMS in the field of microfluidics

When it comes to microfluidics or micromachining, almost everyone thinks of PDMS or polydimethylsiloxane. However, since George Whitesides first introduced PDMS to microfluidic technology in 1998, PDMS has become the primary material of choice and plays a vital role in microfluidic technology. This article reviews some of the advantages of PDMS and the part of [...]
