Encapsulation of Piper aduncum and Piper hispidinervum essential oils in gelatin nanoparticles: a possible sustainable control tool of Aedes aegypti, Tetranychus urticae and Cerataphis lataniae

Abstract

The present work successfully developed gelatin-based nanoparticles that served as carriers for the EOs of P. aduncum and P. hispidinervum to be applied as a sustainable control tool of A. aegypti, T. urticae and C. lataniae. The developed loaded nanoparticles presented high encapsulation efficiency and EO concentration release higher than lethal dosages. This indicates that it is feasible to use gelatin-based nanoparticles loaded with P. aduncum and P. hispidinervum EOs to control the tested pests. © 2018 Society of Chemical Industry.

Recent Developments in Nanotechnology for Detection and Control of Aedes aegypti-Borne Diseases

“…Results showed a high encapsulation efficiency of the EOs (around 80%), average size around 100-200 nm, zeta potential around−40 mV. Both encapsulated EOs reached lethal dosages within 24 h of exposure and total mortality of the tested pests (Silva et al, 2019).…”

“…The results showed that the release mechanism was temperature dependent, which the authors highlighted as having great potential, since the release rate could be adjusted by alteration of temperature (Gomes et al, 2018). Silva et al (2019) encapsulated essential oils of Piper aduncum L. and Piper hispidinervum in gelatin nanoparticles and evaluated effect against Aedes aegypti Linn. Results showed a high encapsulation efficiency of the EOs (around 80%), average size around 100-200 nm, zeta potential around−40 mV.…”

“…The encapsulation efficiencies exceeded 80%, and the particles were spherical, monodispersed, and smaller than 100 nm in size. Both of the encapsulated essential oils provided lethal effects within 24 h of exposure, with Aedes aegypti mortality greater than 80% (Silva et al, 2019).…”

Piper Species: A Comprehensive Review on Their Phytochemistry, Biological Activities and Applications

“…Dos Santos et al [74] describe EOs mainly composed of sesquiterpenoids, and da Silva et al [32] describe an EO rich in monoterpenes (α-pinene at 15.3% and β-pinene at 14.8%). A Piper hispidinervum (sic) leaf EO contained 53.98% sesquiterpene hydrocarbons, 33.06% of monoterpenoids and no trace of phenylpropanoids [47]. Table 18 summarizes the data on the main compounds of P. hispidum (and P. hispidinervum) leaves.…”

Engenharia Biomédica Como Ferramenta Para O Controle Biológico De Arboviroses

“…Os óleos essenciais são extraídos de folhas, caules, sementes e flores de várias espécies da flora brasileira em especial da amazônica, porém sua utilização para tecnologia na região norte ainda não é satisfatória comparada a outras regiões do Brasil, apesar de que as maiores concentrações das espécies ricas em óleos essenciais encontram-se no Norte do país. A quantidade de óleo essencial extraído da espécie Piper é abundante, além das múltiplas funções biológicas e diversas aplicações, inclusive na medicina tradicional (SILVA;BASTOS, 2007). A Amazônia possui um dos maiores ecossistemas mundiais com uma ampla variedade de plantas ricas em óleos essenciais com funções bioativas e medicinais (ANDRADE; GUIMARÃES; MAIA, 2009; TAKEARA, 2017).…”
