基于細(xì)胞的研究背后有許多驅(qū)動(dòng)因素,包括組織工程、體外毒理學(xué)、藥物遞送以及抗菌涂層。
表面等離子共振分析儀最初用于蛋白質(zhì)相互作用的測(cè)量。直到最近,研究人員才開(kāi)始開(kāi)發(fā)SPR用于測(cè)量活體細(xì)胞。我們很自豪成為第一家能夠測(cè)量跨細(xì)胞和細(xì)胞旁攝取的SPR制造商。
BioNavis和赫爾辛基大學(xué)一起開(kāi)創(chuàng)了藥物和納米粒子-細(xì)胞相互作用的測(cè)量。我們的許多用戶使用MP-SPR測(cè)量細(xì)胞在不同生物材料和涂層上的擴(kuò)散和附著。MP-SPR還可用作檢測(cè)細(xì)胞特定代謝產(chǎn)物的生物傳感器,以確認(rèn)細(xì)胞分化和/或細(xì)胞功能。同樣,一些小組正在研究生物膜的形成或抗菌涂料。
選擇MP-SPR用于活細(xì)胞的五個(gè)原因:
1、能夠?qū)崟r(shí)測(cè)量活細(xì)胞和細(xì)菌附著
2、能夠無(wú)標(biāo)記區(qū)分滲透和內(nèi)化
3、表面自由度
4、溫度和剪應(yīng)力控制
5、MP-SPR與電化學(xué)的結(jié)合
MP-SPR可以回答的關(guān)于活細(xì)胞的五個(gè)關(guān)鍵問(wèn)題:
1、這種藥物的藥物吸收途徑是什么?
2、哪種納米粒子最適合藥物輸送?
3、納米粒子或病毒是如何進(jìn)入細(xì)胞的?
4、細(xì)胞附著在表面的動(dòng)力學(xué)是多少?
5、哪種表面對(duì)細(xì)菌生長(zhǎng)最具抵抗力?
