A method is provided for detecting a hybridisation indication indicative of an amount of hybridisation between a set of probe biomolecules provided at a reaction site and a set of sample biomolecules. The method includes supplying the set of sample biomolecules to the reaction site comprising the set of probe biomolecules. The reaction site is heated to cause dissociation of probe/sample-biomolecule-pairs previously hybridized when the set of sample biomolecules were provided to the reaction site. The hybridisation indication is generated based on detecting the dissociation of the probe/sample-biomolecule pairs caused by heating the reaction site.

REACTION DURATION CONTROL FOR REACTION PERFORMED ON BIOMOLECULE SAMPLES
A reaction duration is controlled for a reaction performed on biomolecule samples on an apparatus comprising temperature control circuitry to independently control temperature for respective reaction sites. A higher temperature is applied to a first subset of reaction sites and a lower temperature is applied to a second subset of reaction sites. The reaction is started at a first time and ended at a second time when the reaction duration has elapsed since the first time. The reaction duration is selected depending on an analysis of dependence of an error rate on the reaction duration, the error rate comprising a rate of errors caused by an unreacted fraction of biomolecule samples at the first subset of reaction sites that remain unreacted at the second time and a reacted fraction of biomolecule samples at the second subset of reaction sites that have already reacted at the second time.

ERROR DETECTION DURING HYBRIDISATION OF TARGET DOUBLE-STRANDED NUCLEIC ACID
A series of hybridisations is performed for forming a target double-stranded nucleic acid from initial fragments, where each further hybridisation step hybridises the direct products of a pair of earlier hybridisation steps. For at least one further hybridisation step HF, both of the corresponding pair of earlier hybridisation steps HE comprise an error-detecting type of hybridisation step, which includes an error detecting operation to detect whether the hybridised fragments formed in the error-detecting type of hybridisation step HE comprise at least one erroneous hybridised fragment, and discarding at least part of the erroneous fragment to exclude it from a subsequent further hybridisation step. By detecting and removing erroneous fragments throughout a staged and controlled hybridisation process, erroneous fragments are prevented from diluting the pool of error-free fragments at each hybridisation step, to improve yield.
