1. A method for determination of properties of a biological matrix, said method comprising steps of:
- providing an optoelectronic measurement means for performing optoelectronic measurements of the biological matrix;
providing a receiving means for removeably receiving the optoelectronic measurement means therein, said receiving means comprising a receiving housing for receiving the optoelectronic measurement means, and a measurement window allowing the optoelectronic measurement means to access the biological matrix;
attaching the receiving means to a first surface of the biological matrix, whereby the measurement window defines a second surface of the biological matrix;
attaching the optoelectronic measurement means to the receiving means said attaching including the steps of first engaging corresponding engaging elements on a first side of the optoelectronic measurement means and a corresponding first side of the receiving means in a tilted manner, then secondly engaging corresponding second engagement elements on a second side of the optoelectronic measurement means and a corresponding second side of the receiving means, thereby cooperatively engaging the optoelectronic measurement means and the receiving means, whereby the optoelectronic measurement means accesses the second surface of the biological matrix through the measuring window;
emitting light from the measuring device toward the second surface of the biological matrix;
detecting light scattered by the biological matrix with the optoelectronic measuring means;
determining a measuring value based upon the detected light;
re-emitting light from the measuring device, re-detecting light scattered by the biological matrix, and re-determining a measurement value, within four hours of the emitting, detecting and determining steps.

Abstract
System for determining the properties of tissue parts of a living organism, comprising an optoelectronic measuring device (10) and an attachment device (20) which is opaque to light and surrounds a measuring window (28) through which determinations are carried out. The device (20) has one or several components (26) for reproducibly attaching the measuring device (10) in a direction toward a first surface of the tissue. Other subject matters of the invention are an attachment device (20) and a method for determining the properties of tissue parts with the aid of the claimed system.
