How prevalent are nano particles in our daily lives? This picture is worth at least 1000 words.
In an article titled “Nanoparticle technology turns personal care products toxic

We learn how some particles such as zinc oxide in skin care products formerly tested in a whole particle state and found to be safe, may become toxic in nano form.
Here is a part of that article.
(NaturalNews) Nanoparticle technology has been in popular use by skincare and cosmetics companies now for roughly a decade. The process takes normal sized, visibly detectable particles of materials like mica and other common ingredients and turns them so small they are invisible to the naked eye.What would be the purpose behind micronizing particles? This makes products a more desirable consistency and caters to a perceived consumer demand for particular consistencies and ease of application. A perfect example is the use of nanoparticles of zinc oxide in sunscreens to reduce the “chalk-white” effect that full-sized particles can cause when applied to the skin.
The problem with nanoparticles
Minerals like zinc oxide and titanium dioxide, commonly used in sunscreen lotions, foundation and other liquid types of lotions are harmless in their normal size. They simply sit on the skin rather than absorbing in to the skin since they are too large to penetrate its protective barrier.
However, when these are broken down into nanoparticles which are often smaller than the size of a red blood cell, they are easily absorbed into the skin. There is research showing that nanoparticles of zinc oxide and other ingredients like aluminum collect in parts of the brain and cause cell death.
These particles are so easily absorbed that they are detectable in all areas of the body, including vital organs. Animal studies have shown that when they are applied to the skin, they penetrate tissues and cells causing damage when they begin to build up. The tiny size gives these particles the ability to travel the body extensively and can enhance their toxicity.

The article cites studies of the conversion of particles to nanoparticles and suggests that any benign particle that is reduced to a nanoparticle can become toxic when brought into contact with the human body.

Hey I hear our curious Quantum POP readers say. What about the beneficial nanoparticles? Well here is one.Tiny particles designed to home in on cancer cells achieve tumor shrinkage at lower doses than traditional chemotherapy.
Targeted therapeutic nanoparticles that accumulate in tumors while bypassing healthy cells have shown promising results in an ongoing clinical trial, according to a new paper.
Here is another one.Stanford scientists have used lab-made gold nanoparticles
to highlight malignant tissue in the brain, making it easier for surgeons to cut out tumors while leaving healthy bits in tact. Measuring just five millionths of an inch in diameter, these tiny glistening orbs are injected into the patient and then left to bleed out through leaky blood vessels in parts of the brain that have been damaged by the disease. They then get stuck in the bad tissue itself, marking it out for the scalpel when viewed with the right type of imaging. It’s not totally new — we’ve actually seen gold nanotech deployed against the Big C in stem cells
before, but better to be useful than avant-garde

Obviously more research is and should be done on this subject. Quantum POP would hope that the solution that could be as simple as finding or developing a nanoparticle that is not absorbed into the body and coating anything that is handled by humans with it, that contains nanoparticles that are toxic to the touch.
