Polymer membranes are used in a wide variety of molecular sensing devices many of which are of potential clinical interest. The role of the polymer and the physical properties required of it are, however, rarely clearly defined. An extensive review is presented of the range of polymers whose use as membranes is described in the sensor literature. This forms the basis of an overview of membrane function in potentiometric amperometric and fibre optic sensors. In particular, the interaction of permeability, permselectivity and transmembrane potential is highlighted, together with the role of polymer membranes as matrices for the immobilization of reactive chemical and biological agents.
聚合物膜被广泛应用于各种分子传感设备中，其中许多具有潜在的临床应用价值。然而，聚合物的作用及其所需的物理特性却很少有明确的定义。本文对传感器文献中描述用作膜的聚合物种类进行了广泛综述。这构成了对电位分析法、安培分析法和光纤传感器中膜功能概述的基础。特别强调了渗透性、选择渗透性和跨膜电位之间的相互作用，以及聚合物膜作为固定反应性化学和生物制剂基质的作用。
