Optical Encoding of Silver Zeolite Microcarriers

Highly resolved fluorescent patterns are generated in an individual silver‐exchanged K‐A zeolite crystal using two‐photon excitation (see figure). The high stability, brightness, and spatial resolution of the patterns are an important advantage over the current state‐of‐the‐art techniques in optical...

Description
Summary:Highly resolved fluorescent patterns are generated in an individual silver‐exchanged K‐A zeolite crystal using two‐photon excitation (see figure). The high stability, brightness, and spatial resolution of the patterns are an important advantage over the current state‐of‐the‐art techniques in optical encoding of microcarriers. Therefore, this material shows high potential as a quality and/or safety label to prevent counterfeiting or as an advanced biolabel.
