Sequencing by Hybridization is a class of methods for determining the order in which nucleotides occur on a strand of DNA . Typically used for looking for small changes relative to a known DNA sequence . The binding of one strand of DNA to its complementary strand in the DNA double helix aka hybridization is sensitive to even single base mismatches when the hybrid region is short or if specialized mismatch detection proteins are present. This is exploited in a variety of ways, most notable via DNA chips or microarrays with thousands to billions of synthetic oligonucleotides found in a genome of interest plus many known variations or even all possible single base variations. This idea and the algorithm behind it were devised by Franco Preparata and Eli Upfal of Brown University Computer Science. The type of sequencing by hybridization described above has largely been displaced by other methods, including sequencing by synthesis, and sequencing by ligation as well as pore based methods . However hybridization of oligonuceleotides is still used in some sequencing schemes, including hybridization assisted pore based sequencing, and reversible hybridization.

Sequencing by ligation is a DNA sequencing method that uses the enzyme DNA ligase to identify the nucleotide present at a given position in a DNA sequence. Unlike most currently popular DNA sequencing methods, this method does not use a DNA polymerase to create a second strand. Instead, the mismatch sensitivity of a DNA ligase enzyme is used to determine the underlying sequence of the target DNA molecule. Process DNA ligase is an enzyme that joins together ends of DNA molecules. Although commonly represented as joining two pairs of ends at once, as in the ligation of restriction enzyme fragments, ligase can also join the ends on only one of the two strands for example, when the other strand is already continuous or lacks a terminal phosphate necessary for ligation . DNA ligase is sensitive to the structure of DNA and has very low efficiency when there are mismatches between the bases of the two strands. Sequencing by ligation relies upon the sensitivity of DNA ligase for base pairing mismatches. The target molecule to be sequenced is a single strand of unknown DNA sequence, flanked on at least one end by a known sequence. A short anchor strand is brought in to bind the known sequence. A mixed pool of probe oligonucleotide s is then brought in eight or nine bases long , labeled typically with fluorescent dyes according to the position that will be sequenced.

Fluid amplifiers rely on a fluid control stream to switch a fluid power stream. Fluid amplifiers are so named because a low energy fluid control signal can control and switch a high energy fluid power stream to produce an output signal of higher energy level than the fluid control signal.
