Global colloidal gold market trend 2024-2030 What is Colloidal Gold Used For? by Newsadannews

Chile's government is considering phasing in a proposed ban on glacial mining to limit projects high in the Andes by some big copper companies. Chile's constitutional assembly has approved a proposal to ban mining in glaciers, protected areas, and areas vital to protecting the country's water system.

Chile's mining minister, Marcela Hernando, said about 20 mines had been identified in protected areas, some close to glaciers, including Codelco's El Teniente and Andina projects and Anglo American Plc's Los Bronces project.

The new measures for glaciers and other protected areas will put about a fifth of Chile's copper colloidal gold prices are predicted to increase in the next few days.

Tumor detection 
In cancer research, colloidal gold can be used to target tumors and detected in vivo using SERS (Surface-enhanced Raman spectroscopy). Surrounded by Raman reporter molecules, the gold nanoparticles emit light 200 times brighter than quanta. It found that Raman molecules were stabilized when nanoparticles were coated with a mercaptan modified polyethylene glycol coating. This allows compatibility and circulation in the body.  To specifically target tumor cells, pegylated gold particles are conjugated with antibody (or antibody) fragments, such as scFv, that target, for example, the epidermal growth factor receptor, which is sometimes overexpressed in cells of certain cancer types. Using SERS, these pegylated gold nanoparticles were able to detect tumor locations. 
Gold nanoparticles accumulate in tumors due to leakage of tumor vasculature and can be used as contrast agents to enhance imaging in time-resolved optical tomography systems using short pulsed lasers for skin cancer detection in mouse models. The spherical gold nanoparticles applied widened the time distribution of the reflected light signal and enhanced the contrast between the surrounding normal tissue and the tumor. 
 
Chemotherapy 
Gold nanoparticles in chemotherapy and radiation therapy are colloidal gold used in therapy, usually for cancer or arthritis. Gold nanoparticles show promise in advances in cancer treatment. Some properties of gold nanoparticles, such as their small size, non-toxicity and non-immunogenicity, make these molecules useful candidates for targeted drug delivery systems. Using tumor-targeted delivery vectors becomes smaller and the ability to bypass the body's natural barriers and obstacles becomes more possible. To increase the specificity and likelihood of drug delivery, tumor-specific ligands can be transplanted to particles along with chemotherapeutic drug molecules to allow these molecules to circulate throughout the tumor without redistributing into the body.
 
Gene therapy 
Gold nanoparticles have shown potential as intracellular delivery vectors for siRNA oligonucleotides with the greatest therapeutic impact. 
Gold nanoparticles have shown potential as intracellular delivery vectors for antisense oligonucleotides (single- and double-stranded DNA) by providing protection against intracellular nucleases and easily targeted functionalization. 
 
Biosensor
Gold nanoparticles are incorporated into biosensors to enhance their stability, sensitivity and selectivity. Nanoparticle properties such as small size, high surface volume ratio and high surface energy can immobilize a wide range of biomolecules. In particular, gold nanoparticles can act as "electron wires" to transmit electrons, amplifying electromagnetic light so that they can act as signal amplifiers. The main types of biosensors based on gold nanoparticles are optical and electrochemical biosensors.

The secretary of Ukraine's National Security and Defense Council said the US arms lease bill to Ukraine has not yet been implemented. This is still in the process and could start from July to September 2022, he said. The approval of this bill is a very positive decision for Ukraine. Aid to Ukraine through lend-lease will eventually come, the question is when.  

In an effort to speed up the supply of weapons to Ukraine, President Joe Biden signed a defense lend-lease bill for Ukraine at the White House on May 9.


Nippon Steel, JFE Steel, and Kobe Steel will work together to develop a steel-making process that uses hydrogen to reduce carbon dioxide emissions without using blast furnaces. Small test furnaces will be built at Nippon Steel's Hwazaki Research and Development Center (Kamiki city, Ibaraki Prefecture) and JFE's East Japan Steel In Chiba (Chiba City). The two test furnaces, which will be operational by 2024-25, will confirm whether ore with high levels of impurities can also operate smoothly.
