Substrate for Bioarray  
 
 ANP-DC1  
 


 
 
 Product Description  
  ANP-DC1 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  
   - DNA chip, Protein chip, Cell chip
 - Sensor substrates for diagnostic area
