बियो Chip

DL is an ink-jet printed DNA microarray substrate, custom designed and printed for your desired application using gold, silver or metal alloys as the metal coating layer. This highly functional substrate provides for higher immobilization of biomolecules (e.g., DNA, proteins, etc), no restrictions on pattern design, high sensitivity and longer shelf life for the DNA Microarray Solutions Provider.

2. Greatly enhanced surface structure using the leading nanotechnology processes - Superior to oligo slides due to a three dimensional Matrix-like surface with nano-metal particles- High immobilization ratio of biomaterial due to higher surface area of nanosized metal particles
3. High sensitivity and immobilization ratio of biomaterial through the use of ink-jet process
Product Characteristics
- Higher surface area with 3- dimensional porous structure- Low background and high immobilization efficiency- Small-to-medium size patterned spots with various diameter size- Metal ink patterned surface with higher stability and long shelf life compared to conventional gold slide- Enhanced signal-to-noise ratio- Mainly custom design
Product Applications
