Nanoparticles have wide range application from analytical/environmental chemistry to medical, agricultural and pharmaceutical areas. In analytical chemistry, nanoparticles are commonly used in the extraction/preconcentration steps to detect low amount of analyte(s) found in complex sample matrices1. Due to the unique nature of nanoparticles such as large surface area, rapid extraction kinetic and high extraction yield, nanoparticles are indispensable adsorbents in modern solid phase extraction (SPE) methods2. These materials offer analytical methods with high selectivity and sensitivity thanks to great surface area and high affinity to the analyte(s) of interest3. Magnetic nanoparticles are one classification of nanoparticles having functionalizable surface, high adsorption capacity and good separation ability due to its manipulation by external magnetic field4. In addition to magnetic nanoparticles, nanoflowers have gained much attention in analytical and environmental sciences due to its flower like structure with many petals providing high adsorption capacity and high surface area5.  Nanoparticle usage in environmental applications mainly includes water and effluent treatment strategies6. Pesticides, heavy metals, dyes, pharmaceuticals and bacteria are some examples to be removed from environmental bodies via nanoadsorbents7. As a result, nanoflowers and magnetic nanoparticles are promising materials in analytical and environmental chemistry.
