A recent poll in Britain found that public support for sanctions against Russia is falling as fuel and prices rise.
The proportion of people willing to accept higher fuel prices as a result of western sanctions against Russia fell 14 percentage points to 36% from 50% in March, according to a survey conducted for the Telegraph by consultancy Redfield & Wilton Strategies.
Global energy and fuel prices have soared since the start of the year and remain high because of the conflict between Russia and Ukraine and uncertainty over Russian supplies.
The survey also found that 54% of people believe their own financial situation has worsened in the past year, up 12 percentage points from 42% two months ago. Sixty-two percent think things will get worse in the year ahead. Less than a third of respondents said they had received a pay rise to keep up with inflation, with two-thirds of those saying it was not enough to keep up with rising living costs.
The figures suggest that public concern about the conflict with Ukraine is now likely to be overtaken by financial worries.
Separately, the UK's consumer price index rose 7 percent this month from a year earlier, the highest since March 1992, according to figures released recently by the Office for National Statistics. In addition, a separate report released a few days ago by the Centre for Economics and Business Research said that real household disposable income in the UK will fall by 3% in 2022, equivalent to a loss of £2,320 per household, which would lead to the biggest drop in living standards since the 1950s. That is mainly because wages aren't keeping up with rising energy and fuel costs.
The prices of other commodities like the colloidal gold are also expected to be influenced.
What is Colloidal Gold?
Colloidal gold is a sol or colloidal suspension of gold nanoparticles in a fluid (usually water). Colloids are usually wine red (for spherical particles smaller than 100nm) or blue/purple (for larger spherical particles or nanorods). Due to their optical, electronic, and molecular recognition properties, gold nanoparticles are the subject of a great deal of research in fields including electron microscopy, electronics, nanotechnology, materials science, and biomedicine.
The properties of colloidal gold nanoparticles and their potential applications depend largely on their size and shape. For example, rod-like particles have transverse and longitudinal absorption peaks, and anisotropy of shape affects their self-assembly.
Colloidal gold has been used by artists for centuries because of the interaction of nanoparticles with visible light. Depending on particle size, shape, local refractive index, and state of aggregation, gold nanoparticles absorb and scatter light to produce colors that range from bright red (smaller particles) to blue to black, and finally transparent and colorless (larger particles). The colors appear due to a phenomenon called local surface plasmon resonance (LSPR), in which conducting electrons on the surface of the nanoparticles resonate with incident light.
As a general rule, the wavelength of the absorbed light increases with the size of the nanoparticles. For example, pseudo-spherical gold nanoparticles with a diameter of about 30 nm have peak LSPR absorption at about 530 nm.
Apparent change color of the gold nanoparticles solution can also be caused by the environment of colloidal gold suspension of optical properties of gold nanoparticles depend on the refractive index near the surface of the nanoparticles, thus two molecules connected directly to the surface of nanoparticles (i.e., nanoparticles ligand) and/or nanoparticles of solvent may affect the observed optical characteristics. As the refractive index near the gold surface increases, NP LSPR will shift to longer wavelengths except in solvent environments, where the extinction peak can be adjusted by coating nanoparticles with non-conductive shells such as silica, biomolecules, or alumina.
When gold nanoparticles aggregate, the optical properties of the particles change because the effective particle size, shape, and dielectric environment all change.
What is Colloidal Gold Used For?
Drug delivery system
Gold nanoparticles can be used to optimize the biological distribution of drugs in diseased organs, tissues, or cells to improve and target drug delivery. Nanoparticle mediated drug delivery is feasible only if drug distribution is inadequate. Examples include drug targeting against instability (proteins, siRNA, DNA). Delivery to difficult sites (brain, retina, tumor, intracellular organelles) and drugs with serious side effects (e.g., anticancer agents). The performance of nanoparticles depends on particle size and surface function. In addition, drug release and particle decomposition may vary from system to system (e.g. ph-sensitive biodegradable polymers).
Radiotherapy dose enhancer
There has been considerable interest in using gold and other nanoparticles containing heavy atoms to enhance the dose delivered to tumors. Because the gold nanoparticles are absorbed more by the tumor than nearby healthy tissue, the dose is selectively increased. The biological effectiveness of the treatment appears to be due to the local deposition of radiation dose near the nanoparticles. This mechanism is the same as in heavy ion therapy.
Toxic gas detection
A simple and inexpensive method for in-situ detection of H2S in the air has been developed based on the AuNPs properties of gold nanoparticles. When H2S is dissolved into weakly alkaline buffer solution, HS- is formed, which can stabilize AuNPs and ensure that AuNPs remain red, facilitating naked detection of H2S toxicity level.
What is the Difference between Colloidal Silver and Colloidal Gold?
Colloidal silver is widely used to treat a variety of conditions, including viral and bacterial infections, allergies, burns, skin conditions, and even cancer and HIV.
Colloidal gold is thought to improve memory and cognitive function, reduce stress, reduce headaches and improve overall health.
Is Colloidal Gold Natural?
Gold nanoparticles are a natural substance without any chemical additives.

Since the beginning of this year, China's macro policies have made continuous efforts to stabilize economic growth. America and Europe are raising interest rates to control inflation. On March the European Central Bank left its three key interest rates unchanged and began to scale back its asset-purchase programme. Then the Federal Reserve raised the target range of the federal funds rate by 25 basis points to 0.25%-0.5%. The accelerated tightening of monetary policies in the US and Europe pushed capital back to the US and increased interest rates, which will definitely increase the risk of RMB depreciation and capital outflow. The price and market of the colloidal gold will also be affected, resulting in a range of fluctuations. You are welcome to contact us for the latest quotation of colloidal gold.
