A cell culture substrate which is durable and which can be readily produced in commercial scale at a low cost, and its production method are provided. The cell culture substrate comprises a substrate and a layer formed by surface modification, which comprises a polymer containing amino group produced by reacting a polymer represented by the following formula (II): (wherein n is 0 or a positive integer, and m is a positive integer, the n and m representing degree of polymerization) formed by chemical vapor deposition of formyl[2.2]paracyclophane represented by the following formula (I): (wherein k is 0 or 1) with a polymer having at least one amino group (—NH2) capable of forming Schiff base in its monomer. The production method of the cell culture substrate comprises the step of synthesizing such polymer on the substrate.

e and n are public information and d is private information. An electronic signature is generated based on a calculated value of e×d mod n. A signature generation apparatus 100 includes a random number generation unit 103, a first calculation unit 111, a second calculation unit 112, and a signature generation unit 121. The random number generation unit 103 generates a random number r. The first calculation unit 111 calculates s1=r×n. The second calculation unit 112 calculates s2=s1+e. The signature generation unit 121 calculates s3=s2×d mod n and outputs s3 as the calculated value of e×d mod n. The signature generation apparatus 100 can thereby generate the above electronic signature securely against differential power attacks.

The present invention provides a method for detection or determination of vitamin C by luminescence that employs a redox-responsive fluorogenic probe consisting of porphyrin or phthalocyanine with a nitroxide radical(s), or that employs a liposome preparation comprising the said redox-responsive fluorogenic probe. The present method can overcome the problems of prior art methods, and in particular, are applicable for bioimaging to allow elucidation of the behavior of vitamin C in vivo.
