Carbohydrate 1—>4-1 inks

A great number of other aHyl compounds have been prepared, especially aHyl ethers and aHyl ether derivatives of carbohydrates and other polymers. They are made by the reaction of hydroxyl groups with aHyl chloride in the presence of alkaU (1). Polymerizations and copolymerizations are generally slow and incomplete. Products have only limited use in coatings, inks, and specialties. Properties of a few aHyl ethers are given in Table 10. 

In the microarray industry, the most commonly used techniques to pattern biologically active molecules are robotic contact printing or ink-jet printing. In general, these methods can fabricate biochips with thousands of different compounds, which can be analyzed simultaneously. The most commonly spotted biomolecules include oligonucleotides,1 proteins,2 and carbohydrates.3 Microarray-based platforms have... 

Chromatogra-phy refers to the separation of materials using their relative solubility and absorption differences in two immiscible phaseS/ one stationary and the other mobile. The defining work of Mikhail Tswett in 1903 demonstrated the separation of colored plant pigments on a carbohydrate powder through which hydrocarbon solvents were passed. The same principles apply to the rainbow-like dispersion of colors seen when ink soaks through a shirt pocket.
