在過(guò)去二十年里,納米技術(shù)因其覆蓋了多學(xué)科領(lǐng)域并且具有改變世界的巨大潛力,對(duì)人類的生活產(chǎn)生了巨大影響。納米技術(shù)是當(dāng)今世界研究熱點(diǎn)之一,在人類日常生活的各個(gè)領(lǐng)域都有廣泛的應(yīng)用。大量納米結(jié)構(gòu)的合成推動(dòng)了多科學(xué)領(lǐng)域的進(jìn)一步深化研究,這些研究領(lǐng)域包括但不限于半導(dǎo)體器件、傳感、太陽(yáng)能電池、生物醫(yī)學(xué)和納米藥物。盡管已經(jīng)合成了許多在電子器件制造方面有潛在應(yīng)用前景的納米結(jié)構(gòu),但是在健康醫(yī)療方面,納米顆粒（NPs）仍然面臨大量的挑戰(zhàn),例如高毒性等。此外,納米顆粒（NPs）在細(xì)胞或組織內(nèi)的積聚也是一個(gè)有待解決的問(wèn)題。為此人們開(kāi)展了復(fù)合的納米顆粒研究,復(fù)合納米顆粒可以同時(shí)執(zhí)行多個(gè)任務(wù),在化學(xué)分析、催化、儲(chǔ)能和藥物等領(lǐng)域具有廣闊的前景。例如,在醫(yī)學(xué)中,復(fù)合納米顆粒可以同時(shí)作為藥物載體和診斷探針。在傳統(tǒng)的藥物輸送系統(tǒng)中,采用口服、靜脈注射或通過(guò)皮膚吸收等模式給藥。這些方法都具有血藥濃度高、載藥/釋藥能力差、靶點(diǎn)選擇性差等缺點(diǎn),具有長(zhǎng)效副作用,危害人類健康。另一方面,慢性疾病如癌癥嚴(yán)重威脅著生命,但其治療在發(fā)展中國(guó)家和發(fā)達(dá)國(guó)家都仍然存在很多問(wèn)題,例如腫瘤和癌癥治療專家在癌癥診斷和治療時(shí)會(huì)遇到多藥耐藥（MDR）限制化...
