We live in a world characterised by excessive use of natural resources and highly polluting production processes. We believe that science and technology are capable, and must provide innovative solutions that serve not only industrial and human purposes, but that are also sustainable and eco-friendly.

It is on this principle that BioQTN Silver Ag was developed.

What is BioQTN Silver Ag?

BioQTN Silver Ag is a silver nanoparticle product (AgNNPs) with wide uses in different sectors and able to give new properties to everyday products. Widely versatile and innovative, this solution stands out for its combination of marine polysaccharides and a non-dangerous and non-polluting reducing agent.


Thanks to its powerful biocidal activity, BioQTN Silver Ag can be used in food packaging, paints and coatings, footwear, cosmetics, textiles, pharmaceuticals and wound dressings.

It can also be used as an electrical conductor and is a key element in the production of conductive inks in the area of flexible electronics.

BioQTN Silver Ag also promotes increased sensitivity and specificity in sensors and biosensors, reducing the cost of analysis.

This innovation also has potential for application in catalysis processes and DNA sequencing, contamination control and water purification, energy generation and information storage.

Real case examples

Thanks to their biocompatibility and powerful biocidal activity, silver nanoparticles
have a range of applications in the health sector.

1. Production of detergents and coating products.
2. Production of shampoos, cosmetics, sunscreens simplifying the manufacture
of cosmetic products and avoiding incompatibilities between ingredients.
3. Integration in the production of wound dressings and surgical sutures.


The presence of silver nanoparticles in plastic containers and films
considerably increases the shelf life of food.

1. Production of plastic resin and paper/cardboard used to produce
containers, plastic films and boxes for food packaging.
2. Production of ceramic water filters with porosity.

Food packaging industry

The physicochemical properties of the silver particles confer
an increase in the capacity to conduct electricity, increasing
the capacity by up to 10 times.

1. Production of conductive inks for use in the field of flexible
electronics, in the manufacture of printed circuit boards (PCI),
power converters and electronic chips.
2. Applications in sensors, biosensors, with increased sensitivity
and specificity and with a lower analysis cost.
3. Manufacture of nanostructured resin with silver particles used
in the manufacture of washing machines and plastics in refrigerators.

Electrical and electronics industry

Used in the production of yarn and fibers with sanitizing properties for the
manufacture of mattresses, clothes and sheets, upholstery and interior
fabrics for automobiles. The fiber integration of these products creates
value in use in the hospital, residential and commercial sectors.

1. The cleaning of mattresses is not a very common practice, the action
of silver nanoparticles contributes to the maintenance of a healthy
environment, preventing the spread of infections.
2. The production of shoe insoles containing silver nanoparticles allows
hygiene and elimination of bad odor.

Textile industry

Silver nanoparticles increase stability and optimize the drying time
of the ink used in 3D printing.
