Nanoparticles can be used in distinct ways due to their versatile properties. The interest in using Lead Oxide nanoparticles has been increasing year by year. It is one of the most industrially used metal oxide nanoparticles.

This blog can help you to get a detailed conception of this metal oxide and its nanoparticles.

What is lead oxide?

Lead contains a lot of oxide forms, such as PbO, PbO2, Pb2O3, and Pb3O4. PbO, or lead monoxide or lead oxide is the most studied form among them. This oxide is one of the amphoteric oxides. It has two polymorphs: litharge and massicot. Litharge has a tetragonal crystal structure, and massicot has an orthorhombic crystal structure. 

Usage of lead oxide

Different structure of lead monoxide or Lead Oxide plays important role in their properties. It occurs in various forms such as nanopowders, nanorods, nanodendrites, nanoplates, nanostars, nanosheets, and nanotubes. This compound is used widely in batteries, pigments and paints, gas sensors, ceramics and glass industries, and synthetic organic chemistry as a catalyst. 

What are metal nanoparticles? 

Metal nanoparticles have a unique physicochemical characteristic that includes a high fraction of surface atoms and high specific surface area. Metal nanoparticles have many properties: electronic, magnetic, optical, and antibacterial. These properties depend on their shape, size, and chemical surroundings. You can control these constructions by using chemical, physical and biological methods.

Methods of nanoparticles characterization

Several methods are used to identify the structural characterization of Lead Oxide nanoparticles such as:

1. UV-visible spectrophotometry: UV-visible spectrophotometer helps to study the optical PbO nanoparticles. This method shows the presence of absorption peaks that are attributed to the bandgap of the PbO nanoparticles with an orthorhombic phase. 

2. X-ray diffraction:  This analytical technique identifies the phases of a crystalline material and provides information about unit cell dimensions. 

3. Fourier transform infrared (FTIR): This method helps to investigate the chemical bonding of Lead Oxide particles. 

4. Energy-dispersive X-ray spectroscopy (EDX): It identifies and quantifies the elemental compositions in a small amount of object. 

5. Thermogravimetric analysis (TGA) and thermogravimetric-differential thermal analysis (TG-DTA): These two methods show the proper calcination temperature. This is important to realize the potential applications that the objects promise.

6. Scanning electron microscopy (SEM): It provides information about the PbO nanoparticles at the nanoscale level. Also, this method is very proficient in studying the dispersion of PbO-NPs in the bulk or matrix.

The new method of PbO nanoparticles

A new and convenient technique has been discovered for the formation of Lead Oxide nanoparticles for biomedical applications. It requires low temperature and water as a solvent and does not need any additives. This is a very simple method based on the reaction of double distilled water and lead. This method is ergonomic, fast, and environment-friendly. 

In this method, the metal provides hydrogen that decomposes the water. It generates the reaction and forms the nanoparticles. These nanoparticles have a diameter range from 50-150 nm with an average diameter of 100 nm. The positive fact about using this method is that it is completely non-toxic.

Metal oxide nanoparticles for biomedical

The new method in nanoparticle production for biomedical performance is highly beneficial for humans. It appears in low toxicity and obtains more efficient therapy and developed diagnostic devices. The metal oxide nanoparticles can be used in biomedical applications for various issues. These include tissue therapy, immunotherapy, dentistry, regenerative medicines, diagnosis, healing wound, and more. 

Significant development in the field of biomedicine has emerged in large areas and numbers. It projects immense application potential and huge market value for Lead Oxide nanoparticles. These nanoparticles can be used to deal with more crucial issues in the upcoming years.
