The invention relates to a security material comprising a carrier and at least one photochromic Protein and/or a mutein of a photochromic protein. The security material is characterized in that it comprises at least one irreversible photosensitive layer on the carrier, and the at least one photochromic protein and/or mutein is contained at least in the at least one photosensitive layer and/or in an optional additional layer. The inventive security material is also characterized in that it is highly forgery-proof, the photochromic biomolecule cannot be removed therefrom in a usable form, and the photochromic biomolecule does not need to be supplied to a large group of clients.

Protective material comprising reversible and irreversible photochemical functional constituents

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.

A process is described for the linker-free covalent coupling of bacteriorhodopsin in a purple membrane form.

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.

Ophthalmologic implant

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.

Method and preparation for the photochromic marking and/or for securing the authenticity of objects

A light modulator ( ) is proposed which has a photochromic layer ( ), which can be activated optically by control light, for modulating signal light, and at least one optically transparent substrate ( ) for the photochromic layer ( ), in which the light modulator ( ) has at least one filter layer ( ), which reflects the control light in a wavelength-selective fashion for the purpose of retroreflecting control light which has penetrated the photochromic layer ( ). The reflecting filter layer ( ) ensures that the control light is utilized efficiently for the photochemical conversion (photoconversion) of the photochromic material, since the control light passes twice through the photochromic layer ( ). The reflecting filter layer ( ) has the function, furthermore, of separating the control light from the modulated signal light such that the modulated signal light can be evaluated without significant interference from the control light.
