There are numerous medicinal and industrial uses for nanoparticles in the detection and treatment of disease. Nanoparticles stand out for their ability to perform multiple tasks and their small size. It is possible to use nanoparticles to deliver drugs to specific sites in the body, as well as to increase cellular absorption. Gold nanoparticles, which are the most extensively investigated of all metallo-nanoparticles, are the focus of this review. Anti-cancer medications are available; however, necrosis of both malignant and non-cancerous cells is a side effect of many of them. The necrosis caused by gold nanoparticles affects exclusively cancer cells. Smaller than human cells, these tailored drug delivery devices can quickly infiltrate tumors and kill malignant cells. Anticancer medicines that have been conjugated with gold nanoparticles are more effective. Due to their photophysical and optical properties, gold nanoparticles are useful in chemotherapy and cancer diagnostics. Proteins, peptides, and nucleic acids can all be used to modify gold nanoparticles. Such devices have a wide range of applications, from biosensors to medication administration.

The environmental movement has organized in the world in time to time in the world within the various parts for the protection and conservation of the environment. The environment is very important for the healthy living and existence of the life on the earth. The environment degradation occurs due to much human activity one of main causes is over population growth. The earth is living life’s home so it depends on environment for many needs like food, shelter, air, water and other needs. So every human of earth has its own duty to protect the environment, in which women also plays important role. In the environment conservation need have protect native plants, birds and animals, it helps in protect environment and prevents extinction. In the environmental conservation the protection, preservation, management or restoration of nature and ecological community that inhibits in nature is very necessary. In the India women has actively participate in the environmental movement like Bishnoi movement, Chipko movement, Apiko movement, Silent valley movement and Narmada Bacho movement. In the world the women like Rachel Carson has write the book ‘Silent Spring’ and make awareness in the people about environment. The women have considered as weaker section of the society but they have raise voice against the environmental degradation. The Indian Sumaira has founded the Awaaz foundation works on noise pollution, its tireless effort in his field she known as ‘Sound Minister of India.’ The Suman Fenimore Cooper has recognized first American female nature writer he observed nature plants, birds and animal life and noted in his books. The Eunice Newton Foote work as American scientist and she conclude first time certain gases warmed and exposed to sunlight and rise carbon dioxide level which change atmospheric temperature and impact on climate. The Almitra Patel work as anti-pollution activist and environmental policy advocate in India. The Saalumarada Thimmaka has known as Indian environmentalist her planted 384 banyan trees in four kilometer stretch on the highway Hulikal and Kundur in Karnataka. The Indian environmentalist Basanti Devi works in Koshi project of Uttarakhand. The Indian environmentalist Tulsi Gowda has planted more than forty thousand trees and actively participates in afforestation program in the Karnataka. This type many women work in the world for the environmental protection and conservation.
