Nanotechnology for cancer treatment is the latest discovery that not only detects the disease in its early stages, but also helps attack the tumor cells without destroying healthy tissue.
Technology today has the answer to every disease. One of their types is nanotechnology. It has the potential to improve the biological ability to eliminate cancer cells and reduce the collateral toxicity of malignant to non-malignant cells.
Cancer is becoming one of the most significant emerging diseases in the world, triggering 7.6 million people Each year, 1
Current Treatment Methods
Cancer treatment currently involves the removal of the tumor by concomitant surgery by therapy for any further growth of malignancy. There are two challenging focuses on cancer:

All about nanotechnology
 Nanotechnology has shown excellent results in cancer treatment and screening. Researchers have discovered that nanotechnology can help the world to overcome cancer soon. The only goal of this newly discovered technology is the distinction between malignant and non-malignant cells.
Researchers from India and America have developed a nanotechnology-based tool that accurately maps and eliminates malignant tumor cells after performing a field test on sick animals. The low-grade laser heats the nanoparticle sufficiently, which weakens growth and reduces other harmful effects.

Fluorescence scanning (contours of the cancerous region) and surface enhanced Raman scattering (growth area precision) are used to develop these new imaging systems for cancer detection.
The nano-solution is said to penetrate into spongy, porous cancer cells, while they do not penetrate through the denser, healthy tissue. The region is exposed to a near infrared laser when the fluorescence camera detects the tumor. At the same time, the Raman imager detects the Raman scattering of the fluorophore, which displays the details of the malignant tumor tissue at a microscopic level. The laser has a photothermal treatment system with high penetration properties. It destroys the targeted tumor cells by the heat of nanoparticles.
The design of this device is derived from a used gold nanoprobe device that carries fluorophore. The gold surface, the fluorophore and the distance between them play a crucial role in the representation of the frequency and intensity of the emitted light to reproduce the Raman image.
Researchers chose DNA sequencing as a carrier. This is biocompatible and has lower potential toxicity concerns. A favorable DNA sequence was selected and the optimal design derived. Fluorophore was stuffed onto the DNA and placed on a gold nanostrip core with a silver layer. This method provides efficient and high-resolution dual imaging of cancer for both internal and external tissue studies. The study on animals has successfully shown the treatment of target tumor cells without affecting the healthy tissue in their body. This will soon be used instead of old high-exposure treatment methods that are detrimental to human health. IIT, Bhilai; TIFR, Hyderabad; Memorial Sloan Kettering Cancer Center, New York; University of Central Florida; City University of New York; and New York University were involved in this dedicated service. The entire study is published in "Nature Communication" and "Science Wire".
