    • An apparatus for detecting the presence of a substance on a surface includes a proximal pump portion and at least one distal probe portion configured to be immersed in a first fluid. The proximal pump portion and the distal probe portion are in fluid communication with one another. The distal probe portion defines a distal tip having an open port to enable the passage of a second fluid therethrough. The apparatus is configured such that passage of the second fluid through the distal tip enables detection of a substance that may be present on the surface based on measurement of a signal correlating to, in proximity to the surface, one or more bubbles generated by the second fluid in the first fluid. A corresponding method of detection includes probing the properties of an interaction zone via outflow of the second fluid medium from the surface.
    • 用于检测表面上物质的存在的装置包括近端泵部分和构造成浸入第一流体中的至少一个远端探针部分。 近端泵部分和远端探针部分彼此流体连通。 远端探针部分限定具有开放端口的远侧末端,以使第二流体能够通过其中。 该装置被配置为使得第二流体通过远侧末端的通过使得能够基于与表面接近的信号的测量来检测可能存在于表面上的物质,所述信号在第二流体附近产生的一个或多个气泡 第一流体中的流体。 相应的检测方法包括通过从表面流出第二流体介质来探测相互作用区的特性。
