Nanotechnology is expected to be the basis of many of the technological advances in the 21st century.

What is nanotechnology?

Research and development around the world is utilising nanoparticle technology in the development of new products and improvement modifications of existing products.

This is a billion dollar market world wide and encompasses almost every electronic, food textile, biomedical and automotive and chemical company.

Of the nanotechnology markets, the US is estimated to possess 28 per cent, Japan has 24 per cent, Western European countries have 25 per cent market share with China, South Korea, Canada and Australia having the remaining 23 per cent together.

What are Nanoparticles?

Nanoparticles are microscopic in size with at least one dimension that measures less than 100 nanometer. One Nanometer is 1 billionth of a meter or 1/25,000,000 of an inch.

These particles are smaller than a red blood cell which is 5000 nm in size. They are 10,000 times narrower than a human hair. They are either naturally occurring in welding, volcanic dust or engineered.

Where is nanotechnology being utilised?

Analytical chemistry is utilising micro filtration of many solid particles to generate new smaller ultra-fine particles used in biomedical, optical and electronic fields.

Some applications include stain-resistant fabrics, strengthening sports equipment, paints, packaging, paper manufacturing, agriculture, health-care, textiles, automotive, energy, transportation, drug carriers, chemotherapy, imaging agents, semiconductor manufacturing, cosmetic delivery such as anti-aging treatments, and household products such as flat screen TVs.

What is the proper personal protective equipment?


In association with NIOSH, the AIHA Protective Clothing Committee has evaluated nanotechnology and made recommendations for PPE which includes gloves.

Nanoparticles can penetrate skin. AIHA in conjunction with NIOSH (National Institute of Occupational Safety and Health) recommends that gloves made of natural rubber, nitrile or vinyl be used. dust masks and protective garments are also recommended.

How do you test nanoparticle penetration?

NIOSH and AIHA references using the existing test ASTM F1671 standard test method for resistance of materials used in protective clothing to penetration by blood-borne pathogens using Phi-X174 Bacteriophage penetration as a test system as a test for penetration by nanoparticles.

Bacteriophage Phi-X174 Model Virus:


This is the model viral particle that is being utilised for testing in Best's complete N-DEX family of products for protection from Blood-Borne Pathogens.

This model virus is 27 nanometers in size and is in fact considered a nanoparticle (less than 100 nm in size).

What does this mean for Best?

Best has had the entire N-DEX product line certified as compliant with NFPA 1999 standard on protective clothing for emergency medical operations, 2005 edition.

This certification is now even more valuable since NIOSH and AIHA have endorsed the use of the viral penetration data in determination of protection from nanoparticles.

Nano-DEX

N-DEX glove family continues to be the answer for many different industries.

As twenty-first-century technology develops at an incredible speed worldwide, Best has the perfect product with proven effectiveness to protect the workers in this huge industry.

Incredible new products that offer hope in cancer research and innovation in all areas of our lives offer great opportunities for Best’s most innovative glove product line, N-DEX.
