Improvement of reliability of molecular DNA computing: solution of inverse problem of Raman spectroscopy using artificial neural networks

Abstract: Elaboration of methods for the control of biochemical reactions with deoxyribonucleic acid (DNA) strands is necessary for the solution of one of the basic problems in the creation of biocomputers-improvement in the reliability of molecular DNA computing. In this paper, the results of the solution of the four-parameter inverse problem of laser Raman spectroscopythe determination of the type and concentration of each of the DNA nitrogenous bases in multi-component solutions-are presented.

“…The most significant changes reflected by Raman bands arise from nucleic acids/nucleic bases at 787, 920, 1205, 1235, 1342 cm -1 . The intense bands at 1342 and 1380 cm -1 are due to guanine vibrations, and the 1380 cm -1 band comes from vibrations of both adenine and thymine 46 . In general, the comparison of averaged Raman spectra of the ER area indicates a trend for increased protein signal.…”

“…Наряду с качественным анализом (например, классификацией типов рака по спектрам ИК поглощения биоткани [10]) применение ММО позволяет строить регрессионные модели для количественного анализа образцов. Например, авторами [11] с помощью применения нейронных сетей к спектроскопическим данным комбинационного рассеяния света была решена трехпараметрическая задача по определению типа и концентрации трех видов азотистых оснований ДНК -аденина, цитозина и гуанина. Полученные точности определения концентраций азотистых оснований ДНК составляли порядка 0.3 g/l, что составляет 1−2% по массе от количества молекул ДНК, участвующих в биохимических реакциях при молекулярных вычислениях.…”
