Release date: 2018-04-20 Swiss News reported on April 19 that AFP reported that a researcher from Switzerland had developed an experimental skin implant that detected subtle changes in the body when it detected subtle changes in the body. It will become darker like a dragonfly, and it may become an early warning signal for early detection of cancer. In the above-mentioned study published in the American medical journal Science and Translational Medicine on the 18th, the researchers said that this implant or "biomedical tattoo" has been tested in the laboratory for about one year and can be identified. The four most common types of cancer, including prostate cancer, lung cancer, colon cancer, and breast cancer. The implant operates by detecting the concentration of calcium ions in the blood, and when a tumor is forming, the calcium ion concentration increases. The researchers pointed out that theoretically about 40% of cancers can be detected in this way. Research author Martin Fussenegger, professor of biological systems science and engineering at the ETH Zurich, told AFP by e-mail that biomedical tattoos can detect high levels of cancer in very early, asymptomatic stages. Blood calcium. If the calcium ions in the blood maintain a high concentration for a long period of time, the biomedical tattoo calcium ion detector will produce an enzyme called tyrosine (é…‰), which converts the amino acid. It is melanin. The expert pointed out that if the artificial sputum is found to be deep, it is time to see a doctor to clarify the cause of the change and to determine the treatment or the type of treatment. Early detection can significantly increase chances of survival. Nowadays, people usually only seek medical treatment when the tumor begins to have problems. Unfortunately, this time is often too late. Fosger said that more research and funding is needed to push the tattoo into human clinical trials, a process that can take up to 10 years.

Intermediate – Intermediate: A material produced during a drug substance processing step that must undergo further molecular modification or refinement to become a drug substance. Intermediates may or may not be isolated. Intermediates are the key products of the previous process of making APIs, which are different in structure from APIs.
Ceftriaxone sodium powder is called preparation, sterile ceftriaxone sodium is called API, and 7-ACA is called intermediate.
Our company specializes in providing key intermediates for various APIs
Intermediate is a very important type of fine chemical products. Its essence is a type of "semi-finished product", which is an intermediate product in the production of certain products. For example, if a product is to be produced, it can be produced from intermediates, saving costs and reducing It is widely used in the synthesis of medicines, pesticides, coatings, dyes and spices. In the field of medicine, intermediates are an important link in the industrial chain of the pharmaceutical industry. They are used for some chemical raw materials or chemical products in the process of drug synthesis. In a word, they are used to produce APIs.
