Functional Magnetic Graphene Composites for Biosensing

Abstract: Magnetic graphene composites (MGCs), which are composed of magnetic nanoparticles with graphene or its derivatives, played an important role in sensors development. Due to the enhanced electronic properties and the synergistic effect of magnetic nanomaterials and graphene, MGCs could be used to realize more efficient sensors such as chemical, biological, and electronic sensors, compared to their single component alone. In this review, we first reviewed the various routes for MGCs preparation. Then, sensors bas… Show more

“…For these reasons, columns and microextraction devices packed with GBMs are usually susceptible to clogging and high backpressures. Likewise, for dispersive techniques, graphene nanosheets are well-suspended in solution, creating difficulty for the sorbent recovery, even after filtration and centrifugation (Hou et al, 2019 ; Li F. et al, 2020 ).…”

“…Это препятствие устраняется созданием нетоксичных высокостабильных магнитных нанокомпозитов (МНК) GrO/магнетик [22]. В ряде работ была показана перспективность использования МНК, созданных на основе оксида графе-на (GrO), для магнитной гипертермии (уничтожения клеток злокачественной опухоли) [23], диагностики в качестве агента, повышающего контрастность снимков магнитной резонансной томографии [24], локализации и лечения посредством целевой доставки лекарств [25]), высокочувствительных биосенсоров [26]. Большое внимание уделяется изучению таких нанокомпозитов, как GrO/FeO [27], GrO/Fe 3 O 4 [28][29][30], GrO/ферриты-шпинели [31][32][33][34].…”

“…Поэтому, для изучения МНК GrO/магнетик используются различные методики (см. например [21,[26][27][28][29][30]), в том числе мёссбауэровская спектроскопия [20,30,33]. Уникальность мёссбауэровской спектроскопии заключается в возможности получения важнейшей информации оксидов железа, определении наличия и процентного содержания магнетита (Fe 3 O 4 ), гематита (α-Fe 2 O 3 ), маггемита (γ-Fe 2 O 3 ), вюстита и других оксидов железа, а также о состоянии ионов железа в исследуемом материале [37,38] [39] и модифицированным в работе [40].…”

“…Biosensors and optical devices are key assets when attempting the early diagnosis and monitoring of disease. The recent advances in functional magnetic graphene composites for making very sensitive and selective biosensor devices are vividly described in the Li et al review [ 10 ]. Due to the enhanced electronic properties and the synergistic effect of magnetic nanomaterials and graphene, MGCs could be used to realize more efficient sensors, such as chemical, biological, and electronic sensors, compared to their single component alone.…”
