A waveguide coated with single-stranded probe nucleic acids and carrying an internally reflected wave signal is contacted with an analyte solution containing denatured test DNA or RNA and fluorescent marker dye. Analyte nucleic acid with sequences homologous to that of the probe polynucleotide will hybridize therewith with concomitant binding of the fluorescent dye to the resultant duplex structures. Fluorescence resulting from the interaction of the wave signal at the waveguide/analyte interface with the signal generating centers created within the space probed by the evanescent component of the wave signal is detected and provides useful information on said sequences homologous to that of the probe nucleic acids.
涂有单链探针核酸并携带内部反射波信号的波导与含有变性测试 DNA 或 RNA 和荧光标记染料的分析溶液接触。 与探针多核苷酸序列同源的分析核酸将与之杂交,同时荧光染料将结合到由此产生的双链结构上。 波导/分析溶液界面上的波信号与波信号的蒸发分量探测空间内产生的信号发生中心相互作用而产生的荧光被检测到,并提供有关与探针核酸序列同源的所述序列的有用信息。

(EN) A waveguide coated with single-stranded probe nucleic acids and carrying an internally reflected wave signal is contacted with an analyte solution containing denatured test DNA or RNA and fluorescent marker dye. Analyte nucleic acid with sequences homologous to that of the probe polynucleotide will hybridize therewith with concommitant binding of the fluorescent dye to the resultant duplex structures. Fluorescence resulting from the interaction of the wave signal at the waveguide/analyte interface with the signal generating centers created within the space probed by the evanescent component of the wave signal is detected and provides useful information on said sequences homologous to that of the probe nucleic acids.(FR) Un guide d'onde revêtu d'acides nucléiques sondes à brin unique, et portant un signal d'onde réfléchi intérieurement, est mis en contact avec une solution d'analyte contenant de l'ADN ou de l'ARN d'essai dénaturé et un colorant fluorescent marqueur. L'acide nucléique d'analyte ayant des séquences homologues à celles du polynucléotide sonde se soumettra à une hybridisation avec celui-ci et le colorant fluorescent se liera de manière concomitante aux structures duplex résultantes. Une fluorescence produite par l'interaction du signal d'onde à l'interface guide d'onde/analyte avec les centres générateurs de signaux créés à l'intérieur de l'espace sondé par le composant évanescent du signal d'onde est détectée et fournit des informations utiles sur lesdites séquences homologues à celles des acides nucléiques sondes.
