Zinc oxide (ZnO) nanoparticles have been widely employed for various pharmacological applications. Several approaches were tried to synthesize ZnO nanoparticles. In this study, ZnO nanoparticles were biosynthesized using terpenoid (TAP) fractions isolated from Andrographis paniculata leaves. Subsequently, the ZnNO 3 (0.1 N) is treated with the isolated TAP fractions to biosynthesize zinc oxide nanoparticles (Zn-TAP NPs). This nanoparticle preparation has been confirmed by the colour change from green to cloudy-white and the peak at 300 nm by UV-Visible spectra. FTIR analysis of Zn-TAP NPs showed the presence of functional group (i.e.) C=O which has further been confirmed by H 1 -NMR studies. From SEM and XRD analysis, it has been found that the hexagonal nanorod particle is 20.23 nm in size and ?17.6 mV of zeta potential. Hence, it can be easily absorbed by negatively charged cellular membrane to contribute for efficient intracellular distribution. Therefore, it is suggested that the synthesised Zn-TAP NPs are more suitable in drug delivery processes.
Sensing ability of caffeine interaction with Phe-Phe annotates (PNTs), is presented (Govindhan et al., 2017; Karthikeyan et al., 2014; Tavagnacco et al., 2013; Kennedy et al., 2011; Wang et al., 2017) [1–5] in this data set. Investigation of synthesized caffeine carrying peptide nanotubes are carried out by FT-Raman spectral analysis and high resolution transmission electron microscopy (HR-TEM). Particle size of the caffeine loaded PNTs is < 40 nm. The FT-Raman spectrum signals are enhanced in the region of 400–1700 cm−1. These data are ideal tool for the applications like biosensing and drug delivery research (DDS).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
