Abstract
Fluorescence label preparation, being the core of sensing and imaging, is the most interesting aspect
of label technology. Using the gamma irradiation technique, a facial method is proposed to prepare
organostarch consisting of polyaniline and starch. Polyaniline was introduced into starch molecules to
form an inclusion complex between V-type starch and aniline monomer. The inclusion complex thus
formed consisted of starch-aniline crosslink caused by gamma irradiation through organostarch
crosslinks. Thus, organostarch develops fluorescence property at 470 nm possibly through the interaction
of aniline and starch, which are both fluorophores. A comparative analysis of variations is performed
in common fluorescent labels of starch and organostarch based on their physico-chemical properties.
X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectrometry were utilized to confirm
the inclusion of polyaniline into starch molecules. Furthermore, using a fluorescence microscope, the
positive implementation of fluorescent organostarch was verified. Fluorescent organostarch can be
synthesized through this simple method and can be widely used for developing biomarkers and
biosensors in food and biomedical industries. Organostarch produces florescence under mild conditions
even without complicated preparations, such as additives for labelling with dye fluorescence. The
intensity of fluorescence of organostarch was 17,000 times that of natural starch.
