Medical femtosecond laser cutting machine for processing biochips
(Click 108 )The main material used in the production of Lab-on-a-chip or microfluidic chips is glass. Due to the microscale characteristics of chips, there are high requirements for laser microfabrication of glass during the manufacturing process.
Due to the brittleness and transparency of glass, it is difficult to perform microfabrication. If conventional tools are used for processing, they cannot meet the requirements of biochips, but medical femtosecond laser cutting machines are fully capable. When the pulse duration is less than tens of picoseconds, the interaction between the laser and the material enters a cold ablation state, and the processing quality and accuracy become very high.
Conventional microfabrication methods, such as photolithography, embossing, and soft etching, have been used to manufacture microfluidic chips. However, when it comes to implementing complex microfluidic chips with multifunctional integration, these processing methods will face significant challenges as they require more process steps and are costly.
The medical femtosecond laser cutting machine can ensure high precision and quality in processing, efficiently processing general-purpose microfluidic chips with multiple functions. The ultra short pulse width provides incredible peak power, allowing for surface and internal modification of bulk materials for marking even in transparent materials.
In addition, the use of biochip femtosecond laser cutting machines can also avoid the formation of heat affected zones, thereby reducing damage to sample structure and performance. This makes biochips have greater application prospects in fields such as molecular diagnostics and drug screening.
