CNT Lab: Technological Innovation for the Circulation of Antimicrobial Matrices

About us - The Nanotechnology CNT Lab is at the forefront of developing antimicrobial and antiviral solutions

CNT Lab’s Nanotechnology Laboratory specialises in producing silver-based antibacterial and antiviral colloids, as well as researching and developing innovative solutions. With an area of 500 square metres, it is one of Europe’s most important private laboratories for silver-based colloid production.

The Laboratory is equipped with six reactors for product production and testing, as well as a dedicated reactor for research and development. Our SynthAg technology allows us to create customised solutions for various applications by producing basic syntheses with advanced technical characteristics.

Laboratory testing, certification, and control.
Production and project development for product realization.

Our Project Work Process


Colloidal silver in Ag+ clusters is produced using the SynthAg system (patented) in engineered reactors.The reactors are located in individual spaces (dark booths), and the SynthAg process lasts 22 hours for 5 litres and 48 hours for 10 litres.


After completion, the synthesis is checked using a spectrophotometer.A sample is then transferred to the microbiological laboratory to verify its antimicrobial efficacy.


The administration selects the project to be implemented.The project manager develops the project outline and trains the staff for research (ingredients) and development (sample testing).The R&D lab creates the prototype,and the sampling laboratory produces a sample of the finished product.


The samples produced are sent to external laboratories for technical validationand then returned to the R&D laboratory for final inspection.

The samples produced are sent to external laboratories for technical validation

Samples are sent to the laboratory. We provide laboratory testing services to ensure the quality and effectiveness of our products. We collaborate with industry companies, end customers, and sector specialists to develop customized projects and find the most suitable solutions for the specific needs of each industry sector.

We constantly research the best technological solutions, such as end-therapy for fertilisers in the agricultural sector, to meet our customers’ needs.

At CNT Lab, we are dedicated to delivering high-quality and innovative matrices. Our commitment to sustainability and safety is reflected in our strict quality control and certified processes, ensuring compliance with the highest standards. We also invest in R&D for ultimate control.
