為納米技術(shù)研究市場(chǎng)提供光學(xué)圖像處理的CytoViva公司將一種新型光譜圖像技術(shù)(HSI)引入到*納米顯微鏡系統(tǒng)中。這種技術(shù)的結(jié)合將幫助科學(xué)家在納米醫(yī)學(xué)和納米材料研究取得重大進(jìn)展。 在過去的幾年里,CytoViva的“納米顯微鏡系統(tǒng)”被很多世界納米技術(shù)研究機(jī)構(gòu)采納,包括世界研究醫(yī)院,約翰霍普金斯醫(yī)學(xué)院、德州安德森癌癥中心、美國(guó)FDA、NASA,NIH等。這一技術(shù)受到廣泛好評(píng),并獲得兩項(xiàng)RD100大獎(jiǎng),一項(xiàng) Nano50 大獎(jiǎng)。
CytoViva?納米熒光高光譜顯微成像系統(tǒng)(HSI),可以同時(shí)提供納米材料及生物樣品的光譜分析和圖像數(shù)據(jù)。該系統(tǒng)在可見-近紅外光譜范圍內(nèi)(VNIR)進(jìn)行數(shù)據(jù)采集,提供定量及定性分析數(shù)據(jù),對(duì)活體細(xì)胞和納米材料的熒光或非熒光成分適用。
雙模式熒光顯微成像系統(tǒng):支持熒光標(biāo)記和非熒光標(biāo)記物質(zhì)同時(shí)觀察;支持無機(jī)物質(zhì)如:liposome,環(huán)碳納米管,及其它納米粒子觀察和組織切片、細(xì)胞的熒光/非熒光成像;支持光譜分析等功能。
CytoViva?是一種應(yīng)用在生物醫(yī)學(xué)和納米技術(shù)研究領(lǐng)域的緊湊,超高對(duì)比度,超高分辨率,實(shí)時(shí)光學(xué)顯微鏡。該CytoViva?的光學(xué)照明系統(tǒng)是*的,取代了標(biāo)準(zhǔn)的顯微鏡聚光器,并提供優(yōu)化的光學(xué)分辨率和檢測(cè)??茖W(xué)家們可以快速,方便地觀察各種各樣的納米材料。觀察到在傳統(tǒng)光學(xué)成像技術(shù)無法觀測(cè)到的,活細(xì)胞和細(xì)菌的細(xì)節(jié)。通過將CytoViva雙模熒光系統(tǒng),研究人員還可以觀察到熒光標(biāo)記的納米顆粒,與無標(biāo)記的細(xì)菌和活細(xì)胞的相互作用。這種*的技術(shù)可以無需計(jì)算機(jī)的特殊處理,只需兩種不同的照明方式和*的軟件程序。
CytoViva?是一種革命性的產(chǎn)品,能夠創(chuàng)造新的熒光和高分辨率結(jié)合的光學(xué)顯微成像,達(dá)到*的水平。這種*的系統(tǒng)使研究人員能夠實(shí)時(shí)的,高分辨率的同時(shí)觀察兩個(gè)熒光和非熒光樣品的結(jié)構(gòu)。擁有CytoViva?,研究人員現(xiàn)在就可以在自己的實(shí)驗(yàn)室,隨時(shí)動(dòng)態(tài)觀察亞100nm的納米材料和生物活體標(biāo)本的高分辨率成像。
CytoViva?將您現(xiàn)有的研究顯微鏡的性能提升到一個(gè)新的水平。
實(shí)時(shí)觀察:
· 活細(xì)胞和納米材料的亞100納米分辨率
· 同時(shí)熒光和非熒光樣品結(jié)構(gòu)
納米高光譜顯微成像系統(tǒng):高光譜成像系統(tǒng)配合納米顯微成像系統(tǒng),可以廣泛應(yīng)用于量化細(xì)胞和組織中的納米材料。該系統(tǒng)捕獲掃描范圍內(nèi)近紅外(400-1000nm)內(nèi)每個(gè)像素的光譜信號(hào);每一像素的完整光譜被CCD采集,光譜分辨率高達(dá)2nm,這些數(shù)據(jù)同時(shí)以光譜曲線和RGB圖像形式呈現(xiàn),每一個(gè)視野的詳細(xì)定量分析可以被執(zhí)行,*的分析軟件可以提供的掃描材料的詳細(xì)光譜信息。適用于納米藥物輸送和納米毒理學(xué)領(lǐng)域。 此高光譜分析方法既支持活細(xì)胞和納米材料的非熒光標(biāo)記,也支持熒光標(biāo)記。
雖然這個(gè)系統(tǒng)是專門設(shè)計(jì)用于支持納米級(jí)的研究,同時(shí)它也支持一個(gè)廣泛的,如細(xì)胞生物學(xué)和傳染性疾病領(lǐng)域的生物醫(yī)學(xué)研究。
