ABSTRACT  

Cancer is a genetic disease caused by proliferation and multiplication of tumor cells in the body. Cancer occurs due to uncontrolled growth and development of tumor cells in the body. There are more than 100 different types of cancers categorized on the basis of the affected tissue or organ of the human body. Cancers can be cured by means of both conventional tonic approaches, i.e., surgery, radiation therapy and chemotherapy, and nonconventional or complementary therapeutic methods, including hormone therapy, immunotherapy, nano therapy etc. These well-established therapeutic interventions specifically target the tumors and either inhibit or slow down the growth rate of cells, but incompetent to completely provide protection and largely distress the normal cells, tissues, and organs.

Nanoparticles at a Glance

ABSTRACT  

Nanoparticles (NPs) synthesis, properties, and application exist in different forms. A nanoparticle is a small particle that ranges between 1 to 100 nm in size. Nanoparticles (can be classified into different classes based on their properties, shapes or sizes. The different groups include fullerenes, metal NPs, ceramic NPs, and polymeric NPs. NPs possess unique physical and chemical properties due to their high surface area and nanoscale size. Their reactivity, toughness, and other properties are also dependent on their unique size, shape and structure. Due to these characteristics, they are suitable candidates for various commercial and domestic applications, which include catalysis, imaging, medical applications, energy-based research, and environmental applications. Heavy metal NPs of lead, mercury and tin are reported to be so rigid and stable that their degradation is not easily achievable, which can lead to many environmental toxicities.

ABSTRACT 

This study used ionic liquids to successfully create a positively charged copper nanocomplex that served as a nanocarrier for chlorhexidine. Interestingly, this nanocomplex may deliver the antibacterial drug with a synergistic outcome. In this study, positively charged zinc nanoparticles (CZNPs) loaded with chlorhexidine were examined using UV-visible spectroscopy, TEM, X-ray diffraction, FTIR, and PSA. The effectiveness of loading, the drug release profile, and the antibacterial properties of chlorhexidine were then assessed. For CZNPs, an average size of 42.65 nm was found. As a result of their consistent release of chlorhexidine, the CZNPs are a more potent antibacterial agent while treating Streptococcus pneumoniae.

Lycopene: A Review on Biological Properties

by with No Comment Others

ABSTRACT  

It is a plant chemical fat-soluble organic pigment known as carotenoid. It is a red color pigment. It is a tetraterpene C40H56. It has non-provitamin A activity. Due to the presence of 11 conjugated double bonds it absorbs light in the UV region. Carotenoids are present in human blood and tissues. It is found in tomatoes and tomatoes product. It is the most potent antioxidant in nature. Its bioavailability depends on food processing or the ingestion of fat.
