AbstractThis research aimed to prepare, characterise and study the effectiveness of two
magnetic graphene oxide-based nanocomposites, namely gellan gum-graphene
oxide (GG-GO-Fe3O4) and pectin-graphene oxide (PEC-GO-Fe3O4) as
nanocarriers for permethrin and cinnamaldehyde insecticide compounds. This
research is divided into three parts, namely preparation, characterisation and
effectiveness studies. Nanocomposites with amorphous structure were
successfully produced based on the existence of conjugation mechanism between
GG and PEC with iron oxide at wavenumber peak 650 cm-1. Results from
thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC)
have shown that the nanocomposites loaded with insecticides are thermally stable.
Performance study of nanocomposites loaded with insecticides towards Aedes
aegypti larvae was analysed through Abbott’s and Probit’s formula via in vitro at
different pH using ultraviolet-visible (UV-Vis) spectrometer. The encapsulation
