As nanomaterials become more common, available, and better understood, they are investigated in various applications, including plant protection. Several research groups have studied the use of different nanomaterials, including metal oxide nanoparticles and carbon nanotubes, as antifungals, but these materials remain in the environment for a very long time with potentially toxic effects. Our group has developed environmentally benign nanoparticles (EbNPs) of lignin, and we are investigating their use as an antifungal agent. Our EbNPs have the potential for a wide range of applications, and have been proven to be efficient antibacterial agents when loaded with silver ions. Preliminary experiments showed that EbNPs were almost as efficient at preventing fungal growth as a commercial chemical, and we are studying the fundamental interactions between all the components to understand these results. Through the use of brightfield and fluorescence microscopy, we are able to track the trends of fungal growth and where the EbNPs are going on the spores or substrate. Using various combinations and concentrations of EbNPs, spores, and Tween 20, we investigate colloidal interactions in solution, and infectivity when applied to Potato Dextrose Agar (PDA) plates. Similar to EbNPs, AQ48 and AQ55 type polyester nanoparticles (NPs) have negative surface charge. In order to understand the charge interactions between spores and NPs we are using treatment of polyester NPs on PDA plates. We are comparing the results of the NP treatments to understand the true nature of their interactions. We observe the effects of all the treatments before and after the inoculation of rose petals with spores for understanding their impact on spores growth and development. Such essential understanding of these interactions will assist in formulating efficient and environmentally benign antifungal products.
