Описан чувствительный и экономически эффективный метод обнаружения гена p53 путем объединения гибридизационной цепной реакции (HCR) с наночастицами золота (НЧ-Au). Длинная структура двойной спирали, созданная HCR, не может адсорбироваться на поверхности НЧ-Au после добавления гена p53. При введении в раствор соответствующего количества Na+  НЧ-Au агрегирует и цвет раствора меняется с красного на сине-фиолетовый. Датчик имеет высокую чувствительность с пределом обнаружения 2 нМ, видимым невооруженным глазом, и пределом количественного обнаружения 0.2 нМ с использованием УФ-видимого спектрофотометра. Сочетание флуоресцентной спектроскопии и гель-электрофореза систематически подтверждает специфичность HCR, индуцированной геном p53. Использование бесферментного, безметкового колориметрического метода для обнаружения гена p53 значительно уменьшает сложность и стоимость эксперимента и может найти применение для раннего массового скрининга генов рака. </p><p> </p></abstract><trans-abstract xml:lang="en"><p>The p53 gene is an important tumour suppressor gene, which has an important impact on the early diagnosis of cancer. Here, inspired by the fact that single-stranded DNA (ss-DNA) can be nonspecifically adsorbed on the surface of nanogold, we report on a sensitive and cost-effective new method to detect the p53 gene by combining hybridization chain reaction (HCR) with gold nanoparticles. The long double helix structure generated by HCR could not be adsorbed on the nanogold surface after the addition of the p53 gene. When an appropriate amount of Na+ is introduced into the solution, the nanogold aggregates and the colour of the solution changes from red to blue-violet. The sensor has a high sensitivity with a detection limit of  2 nM visible to the naked eye and a quantitative detection limit of 0.2 nM using a UV-visible spectrophotometer. Notably, by combining fluorescence spectroscopy and gel electrophoresis, the science and specificity of p53 gene-induced HCR is systematically validated. The use of an enzyme-free, label-free colorimetric method to detect the p53 gene greatly reduces the complexity and cost of the experiment. This study has a broad market application prospect and provides a new method for early mass screening of cancer genes. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>колориметрический датчик</kwd><kwd>безметковый</kwd><kwd>гибридизационная цепная реакция</kwd><kwd>ген p53</kwd></kwd-group><kwd-group xml:lang="en"><kwd>colorimetric sensor</kwd><kwd>label-free</kwd><kwd>hybridization chain reaction</kwd><kwd>p53 gene</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">The work for this paper was supported by the National Natural Science Foundation of China (Grant Nos. 62073299, 12004348, 61801436), Joint Fund of Henan Province Science and Technology R&amp;D Program (Grant No. 225200810071), the Science and Technology Major Project of Henan Province (Grant No. 231100220800), Central Plains Science and Technology Innovation Leaders Project (Grant  No. 224200510026), Henan Province Science and Technology Research Project (Grant Nos. 242102221045, 232102220008, 212102210002).
