摘要:The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.

摘要:A superpolar sorbent network is a sol-gel network of at least one metal oxide precursor condensed and at least one polyhydroxy molecule. The metal oxide precursor is a silicate precursor, aluminate precursor, titanate precursor, zirconate precursor, germinate precursor, or any combinations thereof, and the polyhydroxy molecule has a multiplicity of hydroxyl groups. The polyhydroxy molecule can be an organic molecule derived from nature. The superpolar sorbent network can be used as a particulate or bulk sorbent for sampling or removal of analytes or contaminants from an environment or can be coated on a tube or particulate substrate for use as a chromatographic stationary phase.
