Fabrication of Patterned Fluorescence Images in Electrospun Microfibers

摘要

Recently, generation of patterned fluorescence images based on the "precursor approach" has gained much attention. The concept of the 'precursor approach' is to use different electronic properties between the protected and unprotected forms. For example, a dye molecule is non-fluorescent when the key functional group of the dye molecule is protected with a protecting group. If the protecting group is removed under photoinduced chemical transformation, the fluorescence can be regenerated, allowing patterned fluorescent images in the polymer film by selective removal of the protecting group in the exposed areas. The "precursor approach" allows rapid and cost-effective generation of patterned images in one step, without the need for additional wet developing processes.
