The use of metal and metal oxide nanoparticles is frequently regarded as a potential solution to the issue of bacterial antibiotic resistance. Among the proposed range of nanoparticles with antibacterial properties, copper oxide nanoparticles are of particular interest. Although the antibacterial properties of copper have been known for a considerable period of time, studies on the effects of copper oxide nanomaterials with respect to biological systems have attracted considerable attention in recent years.

This review aims to summarize recent articles (from the last five and mostly the last three years) on the nanoparticle/polymer composites for biomedical applications. Articles on polymeric nanoparticles (NPs) and hydrogel-based systems were not reviewed, since we focused our attention mostly on the composites of polymeric matrix with at least one inorganic filler in the form of NPs.

- - Lung cancer rates in Russia, particularly among men, have declined since the 1990s due to reduced smoking, but recent trends show rising incidence rates, especially in women since 2012, while mortality rates remain stable.
- - The study utilized national cancer reports and the Russian Fertility and Mortality Database from 1965-2021 to analyze changes in lung cancer incidence and mortality, revealing significant shifts starting around 2013 for men and 2012 for women.
- - An increase in the use of CT scans coincides with these trends, suggesting the need for ongoing monitoring to assess the impact of improved diagnostic methods on lung cancer outcomes in Russia.
NSCLC is a very aggressive solid tumor, with a poor prognosis due to post-surgical recurrence. Analysis of the specific tumor and immune signatures of NSCLC samples is a critical step in prognostic evaluation and management decisions for patients after surgery. Routine histological assays have some limitations.

The methods of studying the characteristics of plasma and acoustic oscillations induced by optical breakdown are applied. The methods of assessing the concentration of hydrogen peroxide and hydroxyl radicals, the amount of long-lived reactive species of protein and 8-oxoguanine are applied.
