Description
i.一般式:
で記載される化合物、
ii.アスコルビン酸、
iii.次式:
を包含する群から選択される有機化合物で表面が修飾された二酸化チタンTiO2と、
それに加えて好ましくは過酸化水素の水溶液、
を含有する組成物である。
当該材料を合成するための最初の基材は、未修飾のナノ結晶TiO2であり、これは多様な公知の手順により作製できる。その1つをWangらが提案している(J.Phys.Chem.B、2000、104、93〜104ページ)。電荷移動錯体の形成を伴う、本発明による群から選択される有機化合物の化学吸着によって、100nm未満(透過電子顕微鏡による画像化を用いて推定)の二酸化チタンTiO2粒子の表面を直接修飾する。有機化合物分子と半導体粒子との間で光誘起電子移動が生じる。本発明による光活性コロイドは、高度の分散を特徴とし、懸濁液またはエマルションの形態で生じる。
実施例1に記載のように合成した材料群のうち、修飾物質K−1(K−1@TiO2)、ルチン(ルチン@TiO2)、およびアスコルビン酸(KA@TiO2)で修飾されたTiO2ナノ結晶は、pH=7で安定性を示した。他の材料は凝集を起こし、これはpH>3〜4で沈殿物で現れた。K−1@TiO2のUV−visスペクトルを図1aに示す。他の材料(酸性溶液中で安定)と同様に、K−1@TiO2は、約500〜700nmまでの可視光線の吸収を示す。図2に示す透過電子顕微鏡画像から、材料−分離粒子の均質性が確認され、このことは、数ナノメートル〜20ナノメートルのサイズでは凝集傾向がないことを示している。KA@TiO2材料のUV−visスペクトルを図1bに示す。他の材料(酸性溶液中で安定)と同様に、KA@TiO2は、約600〜700nmまでの可視光線の吸収を示す。ルチン@TiO2溶液のUV−visスペクトルを図1cに示す。この材料は、波長600nmまでの可視光線の吸収を示す。
本発明による群から選択された有機化合物で修飾されたナノ結晶TiO2の存在下で可視光線を照射した際の光分解試験を、ウシ血清アルブミン(モデル・タンパク質として)を用いて実施した。変性条件下ポリアクリルアミド・ゲル電気泳動(SDS−PAGE)の半定量的な方法を用いて、溶液中のタンパク質濃度をモニタリングした。ナノ結晶TiO2の修飾にかかわらず、反応混合物は次のように調製した。
新しい材料が微生物を光不活性化させる能力のアッセイを大腸菌のモデル株に対して実施したところ、本材料にはこの細菌株に対する細胞毒性がないことが実証された。そこで、微生物の光不活性化の効率性を調べる試験を実施した。
ルチンで修飾されたナノ結晶TiO2に基づく組成物の存在下で可視光線下の光分解試験を、ウシ血清アルブミン(モデル基質としてのタンパク質)を用いて実施した。変性条件下ポリアクリルアミド・ゲル電気泳動(SDS−PAGE)の半定量的な方法を用いて、溶液中のタンパク質濃度をモニタリングした。ナノ結晶TiO2の修飾にかかわらず、反応混合物は次のように調製した。
図5a:PBS中のルチン@TiO2+5時間照射
図5b:PBS中のルチン@TiO2+2mM H2O2、5時間照射
図5c:3%H2O2(暗所で5時間後)
PBS中の多様な濃度の細菌株(大腸菌)の懸濁液に、滅菌済のルチン@TiO2コロイド溶液(滅菌済のシリンジ・フィルター0.20μmを通して濾過)(図6a)、またはH2O2(図6b)を添加した滅菌済のルチン@TiO2溶液を加えて、最終濃度0.32g dm−3(TiO2について)に到達させた。結果を、PBSの滅菌済の溶液について得られた結果と比較した(図6c)。
この試験は、色素アズールBの分解をモニタリングするモデル系を用いて実施した。結果を図7に示す。濃度0.32g dm−3の光触媒ルチン@TiO2(四角)、濃度5mmol dm−3の過酸化水素(三角)、および、光触媒と過酸化水素との前述の濃度での混合物(丸)の存在下で、アズールBの光分解を観察した。実験は、以下の条件下で行った:アズールBの最初の濃度は0.8×10−4mol dm−3、420nmカットオフ・フィルターを搭載した高圧水銀ランプHBO−500で照射(露光波長は420<λ<800nm)。
