WebAug 1, 2011 · Fluorescent nanoparticles can provide a controlled microenvironment for fluorophore to protect it from unwanted chemical interactions with substrates in the external medium. In addition, the nano-containers composed of fluorescent nanoparticles have considerable advantages, such as high fluorescence intensity and good photo stability. WebPurpose: To assess whether fluorexon strips could be used in tear stability [tear film break-up time (TBUT)] measures, as compared with fluorescein strips. Methods: The pre-ocular tear film stability was assessed in 40 adults (19-29 years of age), half of whom were adapted soft contact lens wearers, using the dye-assisted tear film break-up time (TBUT) …
