    • A method for the detection of an analyte in a fluid, which comprises contacting the fluid with a holographic element comprising a medium and a hologram disposed throughout the volume of the medium, wherein an optical characteristic of the element changes as a result of a variation of a physical property occurring throughout the volume of the medium, and wherein the variation arises as a result of interaction between the medium and the analyte; and detecting any change of the optical characteristic of the element; wherein (a) the medium comprises a group which is capable of reacting with the analyte, wherein the analyte or the group is capable of existing in a plurality of forms, and the detecting is conducted in the presence of a first catalyst which is capable of catalysing the conversion of a relatively less reactive form of the analyte or group to a relatively more reactive form; or (b) the fluid comprises a component, other than the analyte, which is capable of interacting with the medium, and the detecting is conducted in the presence of a second catalyst capable of catalysing the removal of said component.
    • 一种用于检测流体中的分析物的方法,其包括使流体与包括介质的全息元件和设置在介质的整个体积中的全息图接触,其中元件的光学特性由于变化而变化 在介质的整个体积中发生的物理性质,并且其中由于介质和分析物之间的相互作用而产生变化; 并检测元件的光学特性的任何变化; 其中(a)所述培养基包括能够与分析物反应的基团,其中所述分析物或所述基团能够以多种形式存在,并且所述检测在第一催化剂存在下进行,所述第一催化剂能够 催化相对较少反应性形式的分析物或基团转化成相对更具反应性的形式; 或(b)流体包含能够与介质相互作用的分析物以外的成分,并且在能够催化除去所述成分的第二催化剂的存在下进行检测。
