The global gold nanoparticles market size was USD 99.8 million in 2022 and is projected to touch USD 285.85 million by 2031, exhibiting a CAGR of 12.4% during the forecast period.

Gold nanoparticles also known as colloidal gold when dispersed in water are small gold particles with a diameter of 1 to 100 nm. By reducing chloroauric acid, gold nanoparticles are commonly produced in a liquid. A reducing agent is added to the solution after the acid has been dissolved. By reducing Au3+ ions to neutral gold atoms, Au3+ ions become neutral gold atoms. Increasing the number of gold atoms in the solution causes it to become supersaturated. Sub-nanometer gold particles precipitate as a result. In a vigorously mixed solution, the particles tend to be uniform in size.  Unlike gold particles, these are a wine-red compound with antioxidant properties, as opposed to gold particles that are a yellow inert solid. Several green methods have been used to synthesize gold nanoparticles, including seed-mediated growth methods, ionic liquid synthesis, and hydrazine reduction methods, as well as sodium borohydride reduction methods. In a wide range of fields including electronics, nanotechnology, and biomedicine, these are the subject of substantial research around the world.

Due to their versatile surface chemistry, gold nanoparticles can be coated with small molecules, biomolecules, and polymers. In addition, they have several unique properties, such as high scattering ability, great absorption, and strong optoacoustic signals for use in healthcare. Furthermore, gold nanomaterials can be conjugated into biomolecules to precise target cancer cells, and used for photothermal cancer therapy, which converts the laser light into heat and kills cancerous cells selectively through their tunable optical properties. Due to their selective accumulation in tumor cells and high biocompatibility, nanoparticles are highly used in targeted cancer imaging and therapy.

COVID-19 Impact: Halt on Chemicals and Advanced Materials to Hamper Market 

The global COVID-19 pandemic has been unprecedented and staggering, with the gold nanoparticles market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden surge in CAGR is attributable to demand returning to pre-pandemic levels once the pandemic is over.

As a result of COVID-19, the gold nanoparticles market growth has also been drastically affected. Due to this, the production process has been halted as well as raw materials have been in short supply. In turn, this hampers the trade cycle. The gold nanoparticles market is also being affected by all these factors. Electronics and the medical field both make extensive use of gold nanoparticles. The market for gold nanoparticles has been adversely impacted by the spread of coronavirus, which has caused top electronic companies' and smartphone manufacturers' sales to decline. However, the COVID-19 pandemic has helped the healthcare sector, which has helped the market for gold nanoparticles. Numerous imports and exports were put on hold for a set amount of time as a result of the restrictions and lockdown. Additionally, many projects and facilities were put on hold as a result of travel restrictions and social distance rules. It will be a positive sign for the market in the upcoming years that markets are opening and lockdowns are being lifted in most nations.

Driving Factors

"Expanding Medical Industry to Drive the Market"

The medical industry's high demand for nanotechnology-based therapeutics and diagnostics is increasing the demand for these nanoparticles. Resonance scattering dark-field microscopy makes use of gold nanoparticles to detect microbial cells and their byproducts, bio-image tumour cells, identify receptors on their surface, and study endocytosis. The effectiveness of labelling cells with conjugates is evaluated on a qualitative level in the majority of biomedical applications. One of the few exceptions is the technique for quantitatively evaluating the effectiveness of cell labelling with these nanoparticles that was used to label pig embryo kidney cells with gold nanoshell conjugates.

"Usage of Gold Nanoparticles in X-ray to Drive the Market"

Gold nanoparticles have received a lot of attention as an X-ray contrast agent because of their high X-ray absorption coefficient, simple synthesis process, non-toxicity, and surface functionalization. Iodinated molecules, a common angiographic agent, have a low molecular weight. Despite having a high water solubility and low toxicity, these iodinated aromatic compounds have a short blood circulation time and are quickly excreted through the kidneys. Iodinated aromatic compounds must therefore be injected multiple times, raising the possibility of thyroid dysfunction. They are appropriate for imaging applications because they have a longer vascular retention time than common agents.

Restraining Factors

"Slight Toxicity of Gold Nanoparticles to Restrain the Market"

The toxicity of the nanoparticle core and its capping ligands must be distinguished, even though it has been claimed that gold nanoparticles are naturally non-toxic. Some toxicity might be unique to particular ligands. For instance, cationic ligands in vitro exhibit moderate toxicity. Thus the market is being restrained by stringent guidelines issued by local or national government agencies regarding the use of nanomaterials in various products due to safety, health, and environmental concerns.
