By varying the medium constituents we could control the size and shape distributions of the gold nanoparticles. Nanospheres of diameter 24 +/- 6 nm and 19 +/- 5 nm were produced using DMEM and M199 mediums respectively, nanoneedles of 150 +/- 50 nm using RPMI medium and nanoflowers of 60 +/- 25 nm using IMDM medium, with an overall yield of 91 +/- 2%. A remarkable decrease in the reaction duration (&lt;3 min) was noted, irrespective of the growth mediums used. Fourier transform infrared spectroscopy and zeta potential measurements revealed them to have a common protenacious encapping agent with different overall surface charges of -23 +/- 3, -21 +/- 1, -24 +/- 2, and -20 +/- 1 mV for Au@DMEM, Au@RPMI, Au@IMDM and Au@M199 respectively. X-ray diffraction confirmed the purity and crystallinity of the particles with Bragg peaks at (111), (200), (220) and (311) for gold nanocrystals. This approach could lead to the creative utilization of novel eco-friendly sources for the production and size/shape control of nanoparticles. Moreover, the adopted methodology is absolutely green, robust and facile, offering new insights for sustainable synthesis for various biomedical and engineering applications.

Therefore, an efficient method for the separation of various mixed core-compositions or dissimilar metallic nanoparticles to their pure forms at the nano-bio interface was developed. Various simple core-combinations of monodispersed nanoparticles with dual cores, including silver plus gold, iron oxide plus gold and platinum plus gold, to the complex three-set core-combinations of platinum plus gold plus silver and platinum plus iron plus gold were sorted using step-gradient centrifugation in a sucrose suspension. Viscosity mediated differential terminal velocities of the nanoparticles permitted diversified dragging at different gradients allowing separation. Stability, purity and properties of the nanoparticles during separation were evaluated based on visual confirmation and by employing advanced instrumentations. Moreover, theoretical studies validated our experimental observations, revealing the roles of various parameters, such as the viscosity of sucrose, the density of the particles and the velocity and duration of centrifugation, involved during the separation process. This remarkably rapid, cost-efficient and sustainable strategy can be adapted to separate other cores of nanoparticles for various biomedical research purposes, primarily to understand nanoparticle induced toxicity and particle fate and transformations in natural biotic environments.&lt;/p&gt;
