Chitosan-based neem seed extract nanocapsules: A new approach on enhancing its effectiveness as an insecticide delivery agent

The utilization of nanotechnology in pesticides delivery has aiming to reduce the indiscriminate use of conventional pesticides and to ensure their safe application. The focus of the present research is on the development of a nanoencapsulated neem seed extract with chitosan as an encapsulate introduced through a harmonically ultrasonic wave treatment. The verification of the presence of AI extract and chitosan in the nanoencapsulate obtained and its characterization are critical to be performed. The method advanced provides a successful insertion of AI in chitosan with no variation of its initial properties producing a nanosized material (below than 200 nm) with good size distribution. This study provides a fundamental and critical information for researchers and engineers in the field of nanotechnology especially in terms of nanoencapsulation techniques use to deliver insecticides.
