    • The invention provides a method of detecting the redispersion of particles into a solution by means of FTIR or other optical detection methods comprising the following steps: providing a sensor surface with dry particles; illuminating the sensor surface with light along a first optical path and detecting the light reflected by the sensor surface; providing a liquid to a volume in contact with the sensor surface; and detecting the reflected light while the dryparticles redisperse into the liquid. Therein, the angle between first optical path and sensor surface fulfils the condition of total internal reflection. The present invention also provides an FTIR cartridge for use in said method comprising a sensor surface accessible for FTIR detection, said sensor surface comprising at least one binding area, wherein label particles are situated on said surface.
    • 本发明提供一种通过FTIR或其他光学检测方法检测颗粒再次分散到溶液中的方法,包括以下步骤:向传感器表面提供干颗粒; 用沿着第一光路的光照射传感器表面并检测由传感器表面反射的光; 向与传感器表面接触的体积提供液体; 并且当所述二氧化硅颗粒再分散到液体中时检测反射光。 其中,第一光路和传感器表面之间的角度满足全内反射的条件。 本发明还提供了一种用于所述方法的FTIR盒,包括可进行FTIR检测的传感器表面,所述传感器表面包括至少一个结合区域,其中标签颗粒位于所述表面上。
