BioQTN Silver Ag
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.
