Description
さらに本発明は、フラーレンとリガンドが−C−O−に結合していることを特徴とする水溶性蛍光フラーレン誘導体を提供する。
本発明の他の特徴及び具現例は、以下の詳細な説明及び添付された特許請求の範囲からより一層明白になる。
本発明の詳細な説明などにおいて使用される主な用語の定義は、下記の通りである。
C60フラーレン(MER Co.)を2mg/mLになるようにトルエンに分散させ、前記分散物10mLをフラーレンの最終濃度が0.12、0.25、0.5及び1.0mg/mLになるようにテトラエチレングリコール(TEG)に1:1で各々添加させて撹はんさせた後、前記撹はんされた混合物に水酸化リチウム(LiOH)を75mMになるよう32mgを溶液に添加して常温で20時間撹はんさせた。このように撹はんされた混合物中ピンク色を帯びたフラーレンがゆっくり茶色に変わったことを確認し、反応が完了するとエチレンアセテートを前記混合物に添加して蛍光フラーレン誘導体の沈殿を誘導させた後、遠心分離を利用して蛍光フラーレン誘導体を分離した。前記蛍光フラーレン誘導体が分離した混合物にエタノールを少量添加して、それにエチレンアセテートを過量添加して沈殿を誘導、分離過程をもう二回進行して、最終的に濃い茶色のC60フラーレンの水溶性蛍光フラーレン誘導体を各々製造した。
実施例1と同様の方法で製造して、C70フラーレン(MER Co.)の最終濃度が1mg/mLになるようテトラエチレングリコール(TEG)と混合されたC70フラーレンを用いてC70フラーレン水溶性蛍光フラーレン誘導体を製造した。
実施例1と同様の方法で製造して、C60フラーレンの最終濃度が1mg/mLになるようジエチレングリコールと混合されたC60フラーレンを用いて水溶性蛍光フラーレン誘導体を製造した。
実施例1で製造された水溶性蛍光フラーレン誘導体中C60フラーレンの最終濃度が1mg/mLになるようテトラエチレングリコール(TEG)と混合されたC60フラーレンを用いて製造された水溶性蛍光フラーレン誘導体を電子顕微鏡(SEM、FEI、Sirion、Netherland)で観察した結果、図2に示したように、平均径が10nmであることが分かった。
実施例1で製造されたC60フラーレンの水溶性蛍光フラーレン誘導体を水に分散させた後、UVハンドランプ(UV.LF104L、UVITEC)365nm波長の紫外線を照射して蛍光フラーレン誘導体の蛍光性を測定した。その結果、図5に示したように、可視光線で茶色(または、黄色)を帯びるC60フラーレンの蛍光フラーレン誘導体は、紫外線照射時添加されたフラーレンの量が多いほど青色から橙色を帯びることから、フラーレンの添加濃度が高いほど長波長の蛍光を放出することが分かり、フラーレンの添加濃度が低いほど短波長の蛍光を放出することが分かった。
実施例2で製造されたC70フラーレンの水溶性蛍光フラーレン誘導体蛍光スペクトルを測定した結果、図8に示したようにC70フラーレンを用いた場合も、350nmの紫外線を照射時540nmで800以上の蛍光の強さで光を放出することが示された。
実施例3で製造されたC60フラーレンの水溶性蛍光フラーレン誘導体蛍光スペクトルを測定した結果、図9に示したようにジエチレングリコールリガンドを用いた場合も350nmの紫外線を照射時540nmで250以上の蛍光の強さで光を放出することが示された。
蛍光フラーレン誘導体の分散性と関して、水に分散している蛍光フラーレン誘導体のゼータ電位(zeta-potential)をELS−Z(Otska,Japan)を利用して測定した。C60フラーレン(MER Co.)の最終濃度が、1mg/mLになるように製造された実施例1の水溶性蛍光フラーレン誘導体を用いてゼータ電位を測定した結果、図10に示したように、約−20mVであることが分かった。これは、水溶性蛍光フラーレン誘導体が負電荷(negative charge)を帯びて、極性である水によく分散することが分かり、さらに、濃度を異なるようにして水分散したフラーレン誘導体を観察した時、高濃度(20mg/mL)以下でかたまる現象はなく、黄色の溶液状態で存在することから、フラーレン誘導体の水分散性や溶解度が非常に高いことを確認することができた。
本発明によって製造した水溶性蛍光フラーレン誘導体のバイオイメージング素材としての可能性を確認するために、実施例3で製造された水溶性蛍光フラーレン誘導体を癌細胞である子宮頸部癌細胞株(HeLa cell、KCLB10002、韓国細胞株銀行)に浸透させて、蛍光顕微鏡写真で観察した。図11(a)は、水溶性蛍光フラーレン誘導体を含有している細胞の透過写真であり、図11(b)は、同じ位置で420nm光を励起させ525nmフィルターを利用して得た蛍光写真で、図11(b)を見ると、図11(a)と同じ細胞位置で緑色信号である水溶性蛍光フラーレン誘導体を確認することができる。また、水溶性蛍光フラーレン誘導体の細胞安全性を確認するために、MTT assayを実施した。対照群である水溶性蛍光フラーレンがない細胞と水溶性蛍光フラーレン誘導体の濃度を0.06〜1.0mg/mLに変化させて、細胞に処理した後、細胞生存率(cell viability)を比較した。
