Laser micro/nano-processing technology

Laser micro/nano-processing technique uses short or ultrashort pulse lasers to write two-dimensional or three-dimensional structures on a micro/nano scale on or within a dielectric, semiconductor or metal surface. It is an emerging interdisciplinary subject involving multiple fields including optics, new materials, chemistry, biology and biomedical engineering, etc. Compared with other processing technologies, it has the advantages of high efficiency, low cost and non-contact processing.

Microfluidic technology

Microfluidic technology refers to the use of micro pipe (size of tens to hundreds of microns) processing or manipulate small fluid volume (l) o for up to the system of science and technology involved, is involved in chemistry, fluid physics, microelectronics, new materials, biological and biomedical engineering in the emerging interdisciplinary. Because of its various features such as miniaturisation and integration, microfluidic devices are often referred to as microfluidic chips, also known as Lab on a Chip and micro-Total Analytical Systems. Microfluidics has the following advantages:

  • Reduce reagent usage: save costs and reduce waste
  • Improve surface to volume ratio: good thermal conductivity, reduce reaction time
  • Integrate multiple functional units on a single chip
  • Decrease detection time
  • Extricate from laboratory restrictions
  • High-throughput analysis
  • Low energy consumption
  • Achieve point-of-care testing
