The research is included determination of Fe(II) via its reaction with 1,10-phenanethroline to form light-red complex which is absorbed at λ max =510 nm. Home-made flow injection valve is designed with two loading loops, L1 and L2. A series of studies are conducted represented by fixing physical and chemical optimum conditions, dead volume, repeatability, dispersion coefficient, construction calibration graph, and application of the method. The dead volume is zero for the system which it has high repeatability (n=8) with RSD and SD 0.6 and 0.05 respectively. The dispersion coefficient is 1.68 at the concentration 10 ppm. The range of measurements of calibration graph is (0.05-18.00) ppm with limit of detection (S/N=3) 0.05 ppm.
The recent review conversed about nano-technology. Nanotechnology is very important in the diagnosis and detection of disease, as nanotechnology is the fifth generation that appeared in the world of electronics, the first generation represented in the use of the electronic lamp, including television, then the discovery of the transistor, and the spread of its wide applications and then the use of integrated circuits, which is a very small piece. Nanotechnology today has reduced the size of many devices, increased their efficiency and numbered their functions. Then the microprocessor, which made a huge revolution in the field of electronics by producing personal computers and silicon chips, and then nanotechnology. Nano-size as the material is made by light etching, cutting, scraping and grinding. Chemical methods can be used that start with single molecules as smaller A unit and assembled into a larger structure. The properties of nanomaterials can be examined and studied and their composition is confirmed using a number of devices and techniques.
This review deals with applications of nano-biochemical materials., Due to the failure of some conventional medical treatments to reach the most accurate tissue in the body, especially for cancer patients, many researchers have resorted to finding quick and therapeutic alternatives that directly treat tissue without leaving side effects, with a prior study of the toxicity of some types of nanoparticles in tissue therapy through nanocapsules. Ultra-fine and the capsule material is excreted after performing its tasks and is excreted with urine and excreta. Also, some biochemical treatments affect the stomach and others, so the researchers resorted to using a small nano-capsule that contains a mixture of treatment with a substance that helps to remove the excess from it with the exit, and thus they are substances that do not affect the rest of the body’s other tissues or healthy tissues, if the body gets rid of the excess of them.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
