Abscisic Acid (ABA) is a vital phytohormone that regulates plant elongation, fruit ripening
and senescence. It also plays an important role in plant responses to environmental stress and
pathogens. In this work, self-assembled ABA was utilized as template for the growth of CdSe
nanoparticles. The formed assemblies were functionalized with an organic linker (ethylene diamine) to
enhance the growth of the CdSe nanoparticles on the surface of the nanofibers. The nanocomposites
formed were analyzed by microscopic and spectroscopic methods. It was observed that the formation of
quantum dots was promoted under mild conditions, leading to the formation of uniform nanofibers
coated with CdSe nanoparticles. Further, the nanocomposites were utilized for targeting HeLa cells. We
believe that such nanomaterials may lead to the development of a new family of nanomaterials for
bioimaging and cancer cell targeting, as well as a host of optoelectronic applications.
