Nanoparticles Are Now in Everything, Including Humans

Nanotechnology, including nanosensors, are now in dust, air, rainwater, plants, soil, food, vitamins, supplements, healthcare, medicine, cosmetics, clothing, and inside the human body. Nanoparticles enter the body through inhalation, absorption into the skin, ingestion, and through medical or dental procedures.

Titanium dioxide nanoparticles (TiO2 NPs) are the most commonly produced and ingested nanomaterial. They are used in food additives, cosmetics, personal care products, and many other things at the commercial level. TiO2 NPs accumulate orally or through inhalation. We are being saturated with semiconductor particles:

"Titanium oxide (TiO2) is a material with wide applications due to its optical and electronic properties. It is used as an ingredient in sunscreen lotions and food products, as a pigment in paints and as semiconductors in the photocatalytic degradation of organic compounds."

Nanotechnology in dust

Smart dust create networks that contain sensors, computer software, wireless communication capabilities and have their own autonomous power supply.

Nanotechnology in air

Many nanoparticles used in aerosol and sprayed into the air are dual purpose, meaning they are capable of more than one function- possible of serving more than one goal. This document on solar radiation modification aerosol spray discusses the "potential applications in biological, electronic, and quantum technologies.”

There is a long list of nanomaterials used in weather modification/geoengineering. Some are capable of affecting the atmosphere while also building nanonetworks inside the human body. However, not all nanomaterials are self assembling once inside the body.

Solar Radiation Management (SRM):

This is also known as solar engineering and involves reflecting sunlight back into space to cool the planet.

Inhaling nanoparticles as a result of Solar Radiation Modification (SRM) using stratospheric aerosol injections is discussed in the document below:


“Using available evidence, we describe the potential direct occupational and public health impacts of exposures to aerosols likely to be used for SRM, including environmental sulfates, black carbon, metallic aluminum, and aluminum oxide aerosols. We speculate on possible health impacts of exposure to one promising SRM material, barium titanate, using knowledge of similar nanomaterials.

Human exposures to materials used for SRM could occur during the manufacture, transportation, deployment and post-deployment of these materials. In this paper, unless otherwise stated, inhalation is the primary route of exposure considered.

Population exposures:

Due to atmospheric circulation and gravitational deposition, large-scale population exposures to atmospherically-injected SRM materials will almost certainly occur after their deployment. Population exposures could also occur through ingestion of food and water contaminated with deposited particles, as well as transdermally. Unlike occupational exposures, there has been virtually no research done to estimate ground-level personal exposures to SRM materials…

In contrast to occupational exposures, population exposures to SRM materials will be continuous and prolonged over months to years, but will likely be orders of magnitude lower than those experienced occupationally. Thus the health effects will be primarily chronic in nature. The use of PPE to reduce personal exposures to deposited SRM materials is not feasible on a population scale."

Nanoparticles in cloud brightening:

This Scientific American article linked below about the same project reads, “The experiment is spraying microscopic salt particles into the air…” Note their misleading use of the word ‘microscopic’. 

Researcher Pete Ramón points out:

“Microscale can never be nanoscale in terms of measurement. When non-scientific authors use micro- to describe nano- they're wrong, but when scientists in the field use micro- to describe nano-, it's intentionally misleading/confusing the reader. That said, nanomaterials can be coagulated/agglomerated/grown to create micro-sized materials. Also, creating nanomaterials from micro can also be done via techniques such as ablation and sonication.”

Geoengineering Test Quietly Launches Salt Crystals into Atmosphere (2024)

This article linked below reads, “Developing a new cloud-aerosol research instrument for use in small-scale field studies. This new research instrument generates controlled volumes and sizes of tiny, sub-micrometer seawater particles in sufficient numbers to increase the local brightness of low clouds in a marine environment"

Researcher Pete Ramón points out their use of the word “sub-micrometer” means by definition that it is nanoscale. If it’s in the nanoscale, we are talking about nanoparticles. Specifically, nanoparticles being released into the sky.

Marine Cloud Brightening Program


Salt particles ranging in size from 30-100 nanometers are the most effective for spraying.

Nanoparticles in cloud seeding:


Water molecules in the atmosphere are too small to combine on their own to form cloud droplets. To form condensation, they need something larger to condense on (preferably flatter surface and at least one micrometer in size). That’s where cloud condensation nuclei (CCN) come in, otherwise known as cloud seeds.


Cloud seeds, or cloud condensation nuclei (CCN), are created by new particle formation (NPF), which are created by even smaller particles forming together.


“Nucleation” sums up this process, where extremely small aerosol particles form larger particles in the sky. 


The scale of nucleation in the atmosphere ranges in the pico-/nano- scale of measurement. NPF may sometimes begin as tiny as picoparticles, build into nanoparticles, then cluster into bigger microparticles.


Atmospheric nanoparticles are referred to as Aitken nuclei by The American Meteorological Society (named after John Aitken).

Ship Tracks:

Nanoparticles from sea vessels are released into the air in the form of “ship tracks”, streaks of clouds from shipping emissions that can reach several miles wide and several hundred miles long.

“‘Ship tracks' above the northern Pacific Ocean. These patterns are produced when fine particles from ship exhaust float into a moist layer of atmosphere. The particles seed new clouds or attract water from existing cloud particles.

Fuel additives

Nanoparticles in the form of multi-walled carbon nanotubes (MWCNT), single-walled carbon nanotubes (SWCNT), graphene nanoplatelets (GNP), and metal oxides such as cerium oxide (CeO2) are used in fuel additives for internal combustion engines in planes, buses and ships. This is another example of dual purpose technology. The nanoparticles in fuel combustion release nanoparticles in the exhaust.


Nanoparticle Fuel Additives:


Sulfur as a fuel additive to create aerosol in planes is discussed here. "Options for dispersing gases from planes include the addition of sulfur to the fuel, which would release the aerosol through the exhaust system of the plane, or the attachment of a nozzle to release the sulfur from its own tank within the plane, which would be the better option.”

Nanotechnology in soft drinks

"Foodborne nanoparticles (NPs) have drawn great attention due to human health concerns. This study reports the detection of the presence of fluorescent NPs, about 5 nm, in two of the most popular beverages, Coca-Cola (Coke) and Pepsi-Cola (Pepsi). The NPs contain H, C and O, [three elements with a tunable emission] and with a quantum yield of 3.3 and 4.3% for Coke and Pepsi, respectively. The presence of sp3-hybridized carbon atoms [carbon quantum dots] of alcohols and ethers bonds was confirmed by NMR analysis…The biodistribution study in major organs indicated that the NPs [nanoparticles] were easily accumulated in the digestive tract, and they were able to cross the blood-brain barrier and dispersed in the brain."
