These nanoparticles have obtained eminence because of their potential efficacy, shape, and size. In the field of nanoscience, the use of natural resources is an emerging topic of interest that has been taken into consideration due to the presence of a reservoir of a priceless wellspring of novel and new chemical entities that have a therapeutic effect. The system has found its space in the treatment of many diseases, including Diabetes, Neurological disorders, Cardiovascular Disorders, and even cancer. At present, cancer is one of the most common causes of death all over the world. Various drugs are used to treat numerous types of cancers, but at the same time, they are found to be harmful to the patient and produce several side effects. To meet the gap, herbal nanoparticles have been studied and are found to be non-hazardous and environmentally friendly. Herbal nanoparticles are synthesized to target various biological pathways that induce cancer and pieces of evidence have shown comparable efficacy like other drugs that have been used conventionally for cancer treatment.

The treatments available to treat cancer include chemotherapy, surgery, and radiation therapy. These treatments are utilized in combination while the most preferred treatment is chemotherapy. Because of the non-specificity of anticancer drugs, they kill healthy cells along with cancer cells, which lead to severe side effects. To minimize such limitations associated with conventional chemotherapy, nanostructured lipids carriers (NLCs) can be developed. These are the nanocarriers consisting of a mixture of solid and liquid lipids and surfactants. Lipids utilized in the formulation of NLCs are biocompatible and biodegradable. NLCs ensure high drug payload, less drug expulsion, and more stability on storage. NLCs enhance the aqueous solubility of lipophilic anticancer drugs. Their surface modification can help to overcome drug resistance in cancer therapy. Controlled and targeted drug delivery of anticancer drugs can be possible by formulating them as NLCs. NLCs can play an important role in targeting anticancer drugs by different mechanisms.

However, the emission and absorption properties strongly depend on the size of the ZnO nanoparticles which in turn depends on the morphology of the nanostructure. Therefore, it is very much important to understand to structure-property relationship for predictable device performance.\u0000\u0000\u0000\u0000Our objective of this work is to synthesize flower-like ZnO nanostructures using simple hydrothermal method. The flower-like ZnO morphology offers large surface area that will be very suitable for designing gas and chemical sensor devices. Other objective of this work is to study the crystallography of ZnO.

A chloride decomposition scheme has been used to produce zinc hydroxide ions that will produce ZnO nuclide. At the onset of saturation, ZnO nanocrystals start to grow. The entire reaction was performed inside a teflon cell stainless steel autoclave. The autoclave was placed in a horizontal tube furnace and maintained at 150 °C for 2 hr resulting the formation of white powder-like material.\u0000\u0000\u0000\u0000The X-ray diffraction data confirms the formation of polycrystalline ZnO having wurtzite structure.

Gibb’s free energy calculation favours the reaction under the experimental condition. The absorption spectrum was used to calculate the band gap of the synthesized ZnO nanoflowers. The Tauc plot revealed the band gap of the synthesized ZnO to be ~ 3.69 eV. This enhancement of band gap compared to bulk ZnO occurs due to quantum confinement effect. The synthesized ZnO nanoflowers exhibit broad photoluminescence peaked at 429 nm owing to the presence of interstitial zinc.\u0000\u0000\u0000\u0000A hydrothermal method has been successfully used to synthesize well-crystalline ZnO nanoflowers of proper stoichiometry.
