摘要:
An ophthalmologic implant for the prophylaxis or treatment of capsule opacification after implantation and completion of wound healing of a synthetic lens is described. This treatment can be repeated if necessary.
摘要:
The invention relates to proton-translocating retinal proteins which exhibit a photocycle which is retarded as compared with the wild type and whose all-trans retinal contents in the light-adapted and dark-adapted states do not differ from each other by more than 10%. The invention furthermore relates to a photochromic composition and to the use of the proton-translocating retinal proteins and the photochromic composition.
摘要:
An optical data store is specified, having a data storage layer with a non-toxic and biodegradable polymer as light-sensitive storage medium which has photo-inducible anisotropy, for the induction of which a threshold value of the optical intensity has to be exceeded. The light-sensitive material is preferably bacteriorhodopsin which, by way of example, is immobilized in a manner embedded in a suitable matrix material or, if appropriate, in a crosslinked manner. The storage medium permits a high storage density and can be applied in a simple manner, for instance by printing onto a substrate.
摘要:
The invention relates to an artificial intraocular lens consisting of a polymer material which permits a change of the optical properties of the artificial intraocular lens when exposed to light. This enables the lens to be exactly adjusted to the required visual acuity upon implantation thereof.
摘要:
The invention relates to a method for producing biomass from halophilic organisms, in which the halophilic organisms are fermented in a hollow space in a salt dome and said halophilic organisms or components thereof are isolated as biomass.
摘要:
A process for the preparation of vinyl, alkynyl or aryl aldehydes or vinyl, alkynyl or aryl ketones by reaction of vinyl-, alkynyl- or aryl- methanols with the aid of a mediator and an oxidant, wherein the mediator is selected from the group of the aliphatic, cycloaliphatic, heterocyclic or aromatic NO or NOH containing compounds.
摘要:
A composition for the delocalized marking of articles, which makes the forging or improper use or exploitation of these articles difficult. It includes chemical elements having a K.sub..alpha. line of from 3.69 keV to 76.315 keV in defined distributions, the physical properties of these substances and/or their elemental and/or quantitative composition serving as delocalized information which cannot be discerned with the naked eye.
摘要:
Method and preparation for the photochromic labeling and/or for protecting the authenticity of objects, in which bacteriorhodopsin materials and preparations therefrom are used for application to the objects; preference is given to using a combination of low-level and high-level security features in said bacteriorhodopsin materials and preparations therefrom.
摘要:
In the case of the electrochemical enzyme biosensor comprising noble metal electrodes, an electrochemical oxidation of pyridine nucleotides takes place, in particular of NADH. The noble metal electrodes have a microtexture rich in surface pores and having catalytic properties, as a result of which the overpotential required for electrochemical oxidation of the pyridine nucleotides is reduced. Owing to these microtextures, the surface area of an electrode is from 3 to 10 times larger than its geometric surface area.
