The invention encompasses a nontoxic agricultural formulation of a concentrated liquid suspension comprising a drying oil and suspended particulate materials, and also encompasses an aqueous formulation comprising the concentrated liquid suspension and an agricultural treatment agent. The invention additionally encompasses methods of treating an agricultural target.

Nontoxic coating concentrates for agricultural uses

A crosslinked self-assembled monolayer (SAM), comprising surface groups containing a nitrogen-heterocycle, was formed on an oxygen plasma-treated silicon oxide or hafnium oxide top surface of a substrate. The SAM is covalently bound to the underlying oxide layer. The SAM was patterned by direct write methods using ultraviolet (UV) light of wavelength 193 nm or an electron beam, forming a line-space pattern comprising non-exposed SAM features. The non-exposed SAM features non-covalently bound DNA-wrapped carbon nanotubes (DNA-CNT) deposited from aqueous solution with a selective placement efficiency of about 90%. Good alignment of carbon nanotubes to the long axis of the SAM features was also observed. The resulting patterned biopolymer features were used to prepare a CNT based field effect transistor.
