Abstract
(EN)
Disclosed is a biological molecule-immobilized carbon membrane which comprises a porous carbon membrane and a biological molecule (e.g., an enzyme) immobilized on the carbon membrane, wherein the porous carbon membrane has pores with a three-dimensional network structure through which a liquid can permeate. The carbon membrane can have a large amount of a biological molecule (e.g., an enzyme) immobilized thereon and can also have a higher level of enzymatic activity or the like compared to a conventional one. Therefore, the carbon membrane is useful as an electrode for a biosensor or a bio-fuel cell.
(FR)
L'invention concerne une membrane de carbone à molécule biologique immobilisée comprenant une membrane poreuse en carbone et une molécule biologique (enzyme, par exemple) immobilisée sur la membrane, ladite membrane poreuse en carbone comprenant des pores formant une structure de réseau tridimensionnelle perméable aux liquides. Une grande quantité de molécule biologique (enzyme, par exemple) peut être immobilisée sur la membrane en carbone, ladite membrane pouvant faire preuve d'un niveau d'activité enzymatique ou autre supérieur par rapport à une membrane traditionnelle. Une telle membrane est par conséquent utile en tant qu'électrode pour biocapteur ou pile à biocombustible.
(JA)
 液体が透過可能な3次元網目状の細孔を有する多孔質炭素膜に、酵素等の生体分子が固定化された生体分子固定化炭素膜が開示される。この炭素膜は、固定化された酵素等の生体分子の量が多く、酵素活性等を従来より高いレベルで有するため、バイオセンサーの電極として、バイオ燃料電池の電極として有用である。
