In this study, the arbuscular mycorrhizal fungus (G. mosseae) and endosymbiont (P. indica) colonized Zea mays were treated with calcium phosphate nanoparticles (CaPNPs) and evaluated for their plant growth promotion efficiency. It was observed that CaPNPs in combination with both G. mosseae and P. indica are more potent plant growth promoter than independent combinations of CaPNPs+G. mosseae,...

Supercritical antisolvent micronization (SAS) is a versatile technique that allows the obtainment of different morphologies and dimensions of precipitates, but only in some cases nanoparticles were produced. This work is focused on the selection of the SAS operating conditions to obtain this morphology. A series of experiments on several compounds and different solvents at 40 °C and selected pr...

This paper reports a surface modification of epoxy-based negative photoresist SU-8 for reducing its autofluorescence while enhancing its biofunctionality. By covalently depositing a thin layer of 20 nm Au nanoparticles (AuNPs) onto the SU-8 surface, we found that the AuNPs-coated SU-8 surface is much less fluorescent than the untreated SU-8. Moreover, DNA probes can easily be immobilized on the...
