Rings of Hydrogel Fabricated by a Micro‐Transfer Technique

Abstract: Microgel rings have been fabricated on a glass surface by a micro‐transfer technique. The polymer melt is transferred to the substrate surface in a confined space with a picoliter volume along the boundary of the polymeric stamp. The surface of the polymer features is smoothened by surface tension in an annealing cycle, which results in isotropic rings. After cross‐linking, the microgels respond swiftly when immersed in water. Asymmetric rings are also obtained by tilting the substrate. The microgels can detac… Show more

“…Using the fabricated high-resolution polymer pattern as a mask, subsequent materials are etched to obtain a high-resolution pattern with the desired material. [137][138][139][140][141][142][143][144][145] As a result, as shown in Figure 4d, a very thin line pattern can be obtained. [146] As with other edge lithography methods, both the effect of reducing the pitch in half and the size of the pattern can be achieved.…”

“…The macroscopic physical gelation of biodegradable copolymers in water has recently been of an especially hot topic because of its potential applications as an injectable biomaterial and also its rich physics as a unique kind of soft matter 2, 4, 17–22. In contrast to many reports for either physical gels or chemical gels so far,1–33 this communication distinguished itself concerning a physical hydrogel with a chemically crosslinked nanogel as the building block.…”

“…Эти понятия для микрогелей были своевременными и конструктивными, так как в дисперсиях стимул-чувствительность обусловлена наличием гидрофильных и гидрофобных фрагментов [22][23][24][25][26][27][28][29][30][31]. Полимеры подобной разновидности, представляющие одну из наиболее интенсивно развивающихся областей современной химии и технологии полимеров, используются в качестве эмульгаторов; дисперсантов; солюбилизаторов; полимерных пленок с молекулярными отпечатками для пьезосенсоров, хроматографических и сорбционных носителей [22][23][24][25][26][27][28][31][32][33][34][35][36][37][38][39][40][41]. Необходимо подчеркнуть, что особое значение для решения указанных проблем было поставлено выдающимся советским химиком Антоном Владимировичем Думанским в 30-50 годах прошлого столетия.…”

“…Эти полимеры внедрены в технологию Ленгмюра-Блождет, осуществляющей перенос мономолекулярных слоев амфифильных органических молекул с поверхности жидкой субфазы на твердую поверхность подложки [17][18][19][20][21][22][23][24][25][26][27][28][29][30]. Макросетчатые и изопористые сверхсшитые полимеры служат в качестве сорбентов в хроматографических анализах, выделениях и разделениях биологически активных добавок, а также токсикантов из крови при гемодиализе [31][32][33][34][35][36][37]41].…”
