Nanomaterials are materials consisting of particles, molecules, or ions with dimensions between 1 and 100 nanometers. They possess unique properties compared to their traditional counterparts because of their atomic-scale size. Because of this size advantage, nanomaterials can be used in many fields, such as electronics, materials science, and consumer products.
Nanomaterials differ from conventional bulk materials because their small size allows them to exhibit unique properties due to the high surface area-to-volume ratio. Examples include:
1. Increased electrical conductivity and higher mechanical strength
2. Making them attractive for use in electronics
3. Sensor technology
4. Biomedical applications
They can also create coatings that make surfaces more hydrophobic or self-cleaning.
Nanomaterials are present naturally in the environment but are also increasingly being produced and used in products. They can be found in various consumer products such as sunscreens, cosmetics, paints, coatings, and food packaging. Medical devices and treatments such as drug delivery systems and cancer therapies also use them.
Nanotechnology has the potential to reduce costs, create more robust and lighter wind turbines, enhance fuel efficiency, and conserve energy due to thermal insulation. It can also enhance early diagnosis and treatment of neurological diseases or cancer since some nanomaterials have specific properties that make them ideal.
Inorganic Nanomaterials (NM), which can be metals or non-metals, oxides, hydroxides, chalcogenides, or phosphates, have a wide range of applications as electronics, photonics, chemical sensors, and biosensors and are vital to our society’s development. Biomedical devices even use them.
Biomedical applications of carbon nanomaterials include treatments, imaging, and diagnostics. Despite this, they still have potentially toxic effects.
Organic nanomaterials are generating a lot of attention from many fields, from clinical research to biotechnology. Their versatility allows them to be used for molecular imaging, drug formulation, and image-guided treatments.
Composite nanoparticles are nanomaterials composed of two or more nanoscale components with unique physical and chemical properties. These components come together to create a unique interface.

There are several studies conducted by The Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR), the European Commission, and EU-OSHA regarding the proven health hazards associated with several manufactured nanomaterials. Although they don’t always have a toxic effect, it requires further assessment individually while research is still ongoing.
The most prominent consequences of nanomaterials have been recognized in the lungs, encompassing inflammation, tissue devastation, fibrosis, and tumor development. Carbon nanotubes may produce asbestos-like repercussions on the cardiovascular system as well. Nanomaterials have been revealed to penetrate other organs and tissues, including the kidneys, heart, brain, skeleton, liver, and softer matter.
During the production stage, workers may come into contact with nanomaterials. Further along the supply chain, more people may unknowingly be exposed to nanomaterials without any safety measures.
Nanomaterials can be inhaled or come into contact with the skin in occupations such as healthcare, laboratories, maintenance, and construction.
Nanomaterial waste is handled the same way as regular waste, without special measures. These nanowastes pose a potentially hazardous or chemically reactive threat, so it’s essential to neutralize them properly before disposing of.
It’s up to the government to have a proactive approach in developing and implementing effective nanowaste management strategies to reduce long-term unintended consequences as much as possible with recycling these materials.
Nanomaterials can be highly hazardous when mishandled, so employers must take the necessary steps to ensure their employees are safe. To minimize risks and protect workers, employers should ensure they understand the hazards associated with nanomaterials and how to manage them effectively.
Here are preventive steps employers can take:
The National Nanotechnology Initiative (NNI) facilitates cooperation among 19 US government agencies on issues related to nanotechnology. The NNI, established by law in 2003, strives to leverage government funds and collaborate between agencies to enhance the nation’s economy, security, and quality of life by advancing science-based technology while preserving public health and environmental integrity.
The European Commission’s Joint Research Centre (JRC) in Europe declared that researchers had considered nanomaterials legislation and identified key requirements for enhanced implementation, including safety and risk assessment.
Nanotechnology is regulated by the Food and Drug Administration (FDA) in the US due to its potential risks in medicines and personal care products.
The US, Japan, South Korea, the United Kingdom, and France are the top 5 countries leading nanotechnology research, discovering innovative ways to use nanomaterials.
They’ve established agencies and initiatives dedicated explicitly to nanotechnology research, such as the NNI in the US, the Nanotechnology Knowledge Transfer Network (NanoKTN), and the National Nanotechnology Centre (NNC) in the UK.
Magnets have proven to effectively remove iron-containing nanoparticles from potentially contaminated mixtures, including wastewater. On the other hand, different techniques have been devised to extract, separate, and reuse pricey gold nanoparticles from various liquids.
