Fumonisin B1 (FB1), the most abundant
component of the fumonisin
family, is highly responsible for fungal infections. In this paper,
our main aim is to study the surface chemistry and spectroscopic properties
of the FB1 molecule and observe the impact of green LED light on the
FB1 Langmuir monolayer. From the surface chemistry and spectroscopic
studies, we found that the FB1 molecule forms a self-assembled Langmuir
monolayer which is sufficient to mimic its interaction with the corneal
tissues. The irradiation of green LED light on the FB1 Langmuir monolayer
showed the degradation of the FB1 when compared to that in the absence
of light. This observation reveals that FB1 molecules lose their tendency
to stay as a Langmuir monolayer. The degradation observed on the interface
was compared with the bulk phase of FB1. The bulk phase observation
also indicated the degradation tendency which reinforced the observed
interfacial property of FB1.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
