ТЭГ-модифицированные наночастицы золота могут выдержать жесткие условия (например, 3 М раствор NaCl) и после их отделения от коллоидов и сушки могут вновь диспергироваться в воде, образуя коллоиды. Обнаружено, что ТЭГ-модифицированные наночастицы золота, полученные из их концентрированных коллоидов, могут спонтанно собираться в двумерную плотноупакованную пленку на границе раздела вода-воздух. Частицы 2D-пленки дают большой воспроизводимый сигнал ГКР при использовании 4-меркаптобензойной кислоты в качестве молекулы зонда, достигая предела обнаружения 1´10- 11  M. На основе этих результатов возможны разработка способа хранения наночастиц золота и изготовление активного субстрата ГКР с высокой воспроизводимостью. </p></abstract><trans-abstract xml:lang="en"><p>Self-assembly of thiolated polyethylene glycol (PEG)-modified Au nanoparticles (NPs) into a closely packed particle film at a water-air interface for the production of reproducible, highly active surface-enhanced Raman scattering (SERS) was developed. Upon modification with thiolated PEG, the Au NPs can sustain severe conditions (e.g., 3 M NaCl solution), and after separation from colloids and drying, they can be redispersed into water, forming colloids again. We found that the thiolated PEG-modified Au NPs, from their concentrated colloids, can spontaneously self assemble into a two-dimensional (2D) closely packed particle film at the water-air interface. With abundant hot spots created and exposed, the 2D particle film produces large, reproducible SERS signal for 4-mercaptobenzoic acid (probe molecule), reaching a detection limit of 1´10-11 M. These results offer a useful way for the storage of Au NPs and the fabrication of highly reproducible and active SERS substrate. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>наночастицы золота</kwd><kwd>тиолированный полиэтиленгликоль</kwd><kwd>самоорганизующиеся наночастицы</kwd><kwd>гигантское комбинационное рассеяние</kwd><kwd>металлические коллоиды</kwd><kwd>Au nanoparticle</kwd><kwd>thiolated polyethylene glycol</kwd><kwd>self-assembly nanoparticles</kwd><kwd>surface-enhaned Raman scattering</kwd><kwd>metal colloids</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">P.
