Targeted photopolymerization is the basis for multiple diagnostic and cell encapsulation technologies. While eosin is used in conjunction with tertiary amines as a water-soluble photoinitiation system, eosin is not widely sold as a conjugate with antibodies and other targeting biomolecules. Here we evaluate the utility of fluorescein-labeled bioconjugates to photopolymerize targeted coatings on...

The examination of haematoxylin and eosin stained sections of normal and neoplastic pituitary glands under ultraviolet light illumination discloses fluorescence of acidophil cells. The distinction between prolactin and growth hormone-producing cells is not possible. Such fluorescence depends on previous eosin staining.

This has developed due to the limited number of licensed products available to treat dermatology conditions. Over time local dermatologists — with support from local pharmacy-manufacturing units — have created a number of unique topical preparations. These are widely used by dermatologists but never scrutinised under research conditions; similarly, it is unlikely that any pharmaceutical company...
