Determining the size of nanoparticles is one of the most important factors in the field of nanotechnology as it defines the unique characteristics of the nanomaterials that are being created for multiple new and valuable applications. Additionally, measuring the size of nanoparticles is vital to furthering our knowledge of air pollution.
Recent studies have revealed that the size of nanoparticles impacts how they move around our bodies, and, ultimately, how exposure to nanoparticles impacts our health. Here we discuss the current methods being used to measure the size of nanoparticles along with the relevance of these methodologies in the development of mano-materials and understanding the impact of air pollution on human health.

Hydrogels offer new hope for cancer treatment
Cancer therapy in recent times relies on the use of several drugs derived from biological sources including different bacteria and viruses, among others. However, these bio-based drugs get easily degraded and therefore inactivated on administration into the body. Thus, effective delivery to and release of these drugs at target tumor sites are of paramount importance from the perspective of cancer therapy.
Recently, scientists have discovered unique three-dimensional, water-containing polymers, called hydrogels, as effective drug delivery systems (DDSs). Drugs loaded into these hydrogels remain relatively stable owing to the network-like structure and organic tissue-like consistency of these DDSs.
