  • Synthesis
  • Liquid Phase Peptide Synthesis is used for the synthesis of very short peptides such as dipeptides, while large-scale Solid Phase Peptide Synthesis is well suited for preparing biologically active peptides including long, difficult and hydrophobic peptides. (biosyn.com)
  • Oligonucleotides are synthesized as unmodified or modified chemical structures with defined sequences using a procedure known as Phosphoramidite solid-phase synthesis. (biosyn.com)
  • Synthetic DNA or RNA oligonucleotides obtained by solid-phase synthesis are employed in a majority of molecular biology applications such as PCR, real-time PCR, sequencing, site directed mutagenesis, single nucleotide polymorphism (SNP) assays, microarrays and various therapeutic applications. (biosyn.com)
  • A recent article [ Mer93 ] has examined the utility of introducing robot-like positional control into the field of synthetic chemistry to achieve molecular manufacturing, which will enable the construction and synthesis of an unprecedented array of desirable materials, including diamond and molecular computers. (n-a-n-o.com)
  • As diamondoid materials put many constraints on their synthesis procedure because they are so highly cross-linked and have such a high bond-density, they probably will have to be synthesized with highly reactive carbon species such as radicals and carbenes, and in a local high vacuum, which are conditions rather far from ordinary laboratory chemistry.
