摘要:The invention pertains generally to the field of biology and particularly to techniques and apparatus for the synthesis and analysis of biopolymers using micro-arrays. The present invention provides improved apparatus and methods in defining the active array locations for each nucleotide-adding operation, enhancing accuracy, flexibility, speed and performance. The apparatus comprises a process chamber, a light source (e.g. laser), a scanning device and at least one sensor unit for detecting the light received. The sensor unit functions as a reference position and may be used for calibrating the light beam. The information for the sensor units is used to compensate.for offset drift, gain drift or loss of laser power. In addition, the present invention relates to the synthesis of biopolymers, e.g. DNA- sequences, peptides, carbohydrates and lipids, carried out using. a patterning process on an activated or chemically inert surface of asubstrate. Non-grid patters are claimed as a non-trivial extension of laser based pattern generation in arrays. Substrates comprising at least one channel and at least one biopolymer at a spatially selected region, which extends over the sides of the channel, are also claimed.

摘要:The present invention relates to a polymerization process for the control of the microstructure of polymers and to novel copolymers. An embodiment of the present invention relates a process of polymerizing first and second monomers in the presence of a complex comprising at least one of the monomers. The presence of the complex modifies the relative reactivity, or cross propagation rate constants, of the monomers in copolymerization reactions. Embodiments of the present invention allow the synthesis of polymers with novel stereochemistry and monomer sequence distribution, for example, but not limited to, copolymers with at least one segment of alternating monomers, a controlled molecular weight and narrow molecular weight distribution, or a segment of high concentration of the first monomer.
