Nanotechnology in Hygiene



Posted on 22nd of December, 2023

Nanotechnology has shown great potential in the field of hygiene and sanitation. From water purification to antimicrobial surfaces, the unique properties of nanomaterials have placed nanotechnology at the forefront of innovative and sustainable hygiene practices.


Nanocoated Surfaces:


Nanocoating refers to the application of thin layers of nanomaterials onto a surface for desired properties and functionalities. A key benefit of nanocoating is the antimicrobial properties of nanoparticles. Silver nanoparticles exhibit strong antimicrobial properties; hence, they are commonly used in coating medical equipment. When applied to surfaces or objects, the layer of nanoparticles acts as a protective barrier that inhibits the growth and survival of bacteria, viruses, and fungi. This not only improves the durability and cleanliness of coated surfaces but also prevents the spread of infection and disease in general.




Nanofabrics are fabrics that have been enhanced or modified using nanotechnology. Similar to nanocoating, nanomaterials are engineered onto textiles to impart specific qualities and functionalities. Nanofabrics with antimicrobial qualities are used for medical textiles, while nanofabrics that possess odour resistance and moisture elimination are used for sportswear and everyday clothing for hygiene purposes. Nanofabrics that incorporate polymer nanofibers have superhydrophobic properties; thus stain- and dirt-proof textiles are possible.


Nanofiltration for Water Purification:


Nanofiltration is a water treatment method that utilizes nanoscale membranes to selectively filter contaminants. With pores ranging only from 1 to 10 nanometres, this method efficiently removes dissolved solids (TDS), including salts and organic matter, while preserving the essential minerals. Nanofiltration excels in treating wastewater and brackish water, more specifically in reducing water hardness. The selective retention of nanofiltration makes it ideal for various industrial applications. A fine balance between purification and resource conservation, nanofiltration remains an efficient solution to the escalating demand for purified water.


Nanoparticle-based Air Purification:


Nanoparticle air purification utilizes microscopic particles to improve air quality. Nanomaterials used in air purifiers commonly include titanium dioxide, zinc oxide, iron oxide, and so on. Due to how the nanoscale dimensions allow for increased surface area and reactivity, these nanoparticles can effectively trap and break down pollutants like bacteria and volatile organic compounds (VOCs). Nanofibers are also used to trap particles and pollutants effectively due to their dense volume and small pore sizes, a physical property common among nanomaterials. This technology is widely used in air purification systems, offering a highly effective and efficient solution for enhancing indoor air hygiene.


Nanotechnology in Oral Care:


The advancement of nanotechnology has enhanced oral care on a microscopic scale. Nanomaterials such as hydroxyapatite nanoparticles have been manufactured into hydroxyapatite toothpaste due to how they mimic natural tooth enamel and promote the remineralization and strengthening of teeth. Besides, zinc oxide nanoparticles are used in root canal sealants to disinfect root canals, while magnesium oxide nanoparticles have shown antimicrobial activity when used as a root canal irrigant. Nano-sized drug delivery systems do exist as well, allowing oral care specialists to target specific issues like sensitivity or gingivitis with precision.


Nanoparticle-based Disinfectants:


Nanoparticle-based disinfectants involve utilizing nanoparticles to enhance disinfection effectiveness. These nanoparticles are often silver nanoparticles and titanium dioxide nanoparticles, which exhibit potent antimicrobial properties. Due to their small size and enhanced reactivity, these nanoparticles can penetrate microbial cell walls, disrupting vital functions and rendering pathogens inactive. This boosts the disinfection process, resulting in a more efficient and rapid means of eliminating bacteria and viruses.
