相比于傳統(tǒng)的熒光染料,半導(dǎo)體熒光量子點(diǎn)具有發(fā)射峰較窄、發(fā)射波長(zhǎng)連續(xù)可調(diào)、抗漂白能力、發(fā)光度、熱等特點(diǎn),利于在實(shí)際和生活中應(yīng)用,如生物學(xué)中作為示蹤劑、在頁(yè)巖氣開采中作為標(biāo)記物等。納米金屬因其的等離子共振效應(yīng),可用其散射效應(yīng)增其周圍發(fā)光物質(zhì)的發(fā)光度,進(jìn)而提檢測(cè)靈敏度;利用其吸收效應(yīng)制成的光熱探針,對(duì)進(jìn)行光熱,是一種非介入、無(wú)痛楚手段。磁性納米材料具有順磁性,可以實(shí)現(xiàn)定向輸運(yùn)、磁分離、增磁共振成像、磁熱等功能。
