Gold nano particles synthesized from Magnolia officinalis and anticancer activity in A549 lung cancer cells. - GreenMedInfo Summary

Nanotechnology is creating a bang in each and every field of life science. Scientists are mounting their interest of research towards gold nanoparticles as they are capable with bigger and advanced properties.Traditionally nanoparticles have been manufactured by various chemical and physical methods but have negative impact on the environment and are also highly toxic. Synthesis of nanoparticles by using plant extracts is substituting the conventional methods and it is eco-friendly too. In the current study, we prepared gold nanoparticles (AuNPs) from Magnolia officinalis, which is identified as an eco-friendly and less toxic method. Incorporation of AuNPs was renowned by UV-absorbance and it shows peak values. Nanoparticle sizes are recognized by dynamic light scattering scrutiny and it shows a value of 128 nm. Besides, high resolution transmission electron microscopy (HR-TEM), energy dispersive X-ray analysis (EDX) and atomic force microscopy (AFM) incorrigibly define the shape of the AuNPs which are present in the complex materials. Fourier-transform infrared spectroscopy (FTIR) findings display that the active molecules are positioned in the plane of the AuNPs. Similarly, anticancer efficacy of AuNPs have been assessed in A549 cells. our study show that AuNPs effectively provoke cytotoxicity, and apoptosis by inflecting apoptotic gene expressions in A549 cells.
