Considering that global loss and waste result in +$1 trillion in annual losses, Metalchemy’s innovative technology couldn’t be more timely. Through its colloids, Metalchemy is transforming preservation and active ingredients. 

What Are Colloids, and Why Do They Matter?

Colloids are mixtures in which microscopic particles are evenly dispersed throughout another substance. These particles, ranging from 1 to 1000 nanometers, do not settle or separate over time. 

The characteristics of colloids, such as their stability, uniform dispersion, and ability to interact at the molecular level, make them invaluable in various applications. There are different types of colloids and examples, including emulsions like mayonnaise, aerosols like hairspray, and sols like paint. 

But at Metalchemy, we focus on colloid examples involving precious metals, specifically silver, gold, and platinum, which offer exceptional properties that go beyond conventional applications.

Colloid Examples 

Metalchemy stands at the forefront of green chemistry, focusing on producing metallic non-nano colloids like silver, gold, and platinum through environmentally friendly methods. Unlike traditional manufacturing processes that often rely on toxic chemicals and high energy consumption, Metalchemy’s patented green process utilizes sustainable practices to create high-quality colloids.

Silver Colloids 

Silver colloids are appreciated for their exceptional antimicrobial and antioxidant action with strong optical absorption around the SPR 419 nm. Metalchemy utilizes silver for applications in high-performance cosmetics and active packaging, where it helps prevent microbial spoilage and significantly extends shelf life.

Gold Colloids 

Gold colloids offer tunable optical properties across the visible to near-infrared (NIR) spectrum, making them ideal for precision applications like phototherapy, medical imaging, and diagnostics such as lateral flow assays and SERS. Their biocompatibility, monodispersity, and ability to be functionalized with peptides, DNA, or antibodies make them powerful tools in targeted delivery and next-generation biosensors. 

Platinum Colloids 

Platinum colloids offer remarkable catalytic activity and redox stability, making them valuable in cosmetics, fuel cells, health care, and sensors. These colloids are not only thermally and chemically stable but also possess anti-inflammatory and antioxidant properties, beneficial in both medical and cosmetic formulations. 

Through these colloid examples, Metalchemy delivers scalable, safe, and sustainable materials that are changing how industries approach preservation, performance, and innovation.

Through the three stages of the Web Summit, we highlighted just how much of a problem food waste is, with an annual loss of $1 Trillion and how colloidal silver can be used to tackle this issue. As well as economical issues, we also spoke in great length about the risks to the environment.

Food waste is a much more prominent issue than a lot of people realise, which is why we’re tackling the problem head on with our active silver packaging. During the summit, we elaborated in detail on the fact that we specialise in silver colloids, derived from an array of organic natural plant extracts, including fresh herbs such as oregano. Silver is renowned for its antibacterial, antimicrobial properties, and we’re harnessing its power to reduce the amount of food we waste as a race. 

Our patented silver colloidal suspension can be used to help inhibit the growth of bacteria. When applied to various packaging materials such as paper, plastics, and bioplastics, the solution creates an environment in which it is incredibly difficult for bacteria to grow and multiply. This means that the food within degrades at a much slower pace, thereby extending its shelf life. 

A Vision for the Future

Colloidal silver is not just limited to food packaging either. In recent months, our company has been expanding our diverse range of colloidal products, while expanding into other markets, including the healthcare, beauty, and cosmetics sectors. 

Recently, we were excited to team up with University College London. Between us, we’re conducting thorough research with the aim of researching medical and cosmetic properties of our colloidal compounds. 

Because of the unique properties associated with our products, including colloidal gold, colloidal silver, and colloidal platinum, our advanced materials can be utilised in various other applications too, particularly when it comes to skincare and cosmetics.

The increased surface area, coupled with the rapid rates of uptake and absorption, means that many of these compounds can be used in skincare and cosmetic creams, and even potentially innovative healthcare solutions according to latest research. 

During the summit, our company’s CEO Federico Trotta also discussed our goals and visions for the future, highlighting how food preservation is only the beginning.

Here’s a quick excerpt of what he had to say at the event. 

‘Our goal is to educate the public about this breakthrough technology, which goes beyond food preservation. We see potential in health, cosmetics, and more. Coming to Web Summit Qatar will help us spread awareness and raise funding to bring this vision to life.’

We’re proud that our mission to use green chemistry to address the global food waste crisis resonated with so many people. It was enough to earn us a spot in the finals among 35 other startups and ultimately bring home the win. 

What’s Next for Metalchemy?

While being very proud of our win in Qatar, as far as we’re concerned, this is only the beginning for Metalchemy.  Our victory at the PITCH Competition has helped open up a wide range of business possibilities, setting the stage for things such as investments, partnerships, funding, and collaborations.

What we’re most excited about however, is that we’re helping to showcase just how powerful silver can be, not as a trading commodity, but rather as a way to tackle the global food waste crisis we find ourselves in. By teaming up with other like-minded companies and innovators who share the same passions as ourselves, between us we can make a real difference. 

One thing that is for certain however, is the fact that things are only getting started for Metalchemy, and the sky really is the limit.
