The practical application of the nanomaterial properties of copper sulfide, nanoparticles are expected to contribute to tumor diagnosis and treatment.
Intelligent deformable nanoparticles are expected to make progress in tumor diagnosis and treatment
For more than three decades, biomedical nanomaterials have been successfully developed for therapeutic diagnostics -- a compound term that refers to the diagnosis and treatment of tumors. Nanoparticles must reach the tumor site and its unique microenvironment to target the tumor.
Recent studies have shown that the physical properties of nanoparticles, especially their size and shape, greatly affect their biological behavior. After the particle circulates through a variety of other healthy physiological microenvironments, these material properties must be controlled to ensure therapeutic release at the tumor site.
These smart shape-shifting nanoparticles are particularly promising for use in tumor therapeutics because their physical properties will adapt to physiology. These adaptations improve particle circulation, biological distribution, tumor penetration, tumor retention, and subcellular distribution of targeted therapies.
"Smart deformable nanoparticles can change their shape under different physiological conditions according to therapeutic needs," said co-author Jianxun Ding. "In our study, we reveal the structural design of these intelligent systems as well as the in-depth mechanisms of transformation."
The researchers use the design of deformable nanoparticles as guidelines for their construction and discuss biomedical applications in the field of therapeutic diagnostics. Ding and his colleagues present their insights through a new classification of nanoparticle transformation design and mechanisms that enable change.
For example, the researchers divided design transitions into two broad categories: size and shape. For transformable nanoparticles, the changes are further divided into small to large and large to small transitions. The study reveals a detailed and rational design of deformable nanoparticles based on their structure.
As for the mechanisms that enable the transformation of nanoparticles, "we think both structure and stimulus make a big contribution," Ding said. "For example, different pH values determine the exact site of transformation, which is associated with different physiological, extracellular and intracellular/lysosomal conditions."
In the past, nanoparticles with constant physical morphology have been widely studied and applied in tumor therapeutics, while recent studies on the transformation of nanoparticles have focused on the response to stimuli. However, until now, there has been no in-depth discussion of the design and application of morphologically convertible nanoparticles.
New materials for a sustainable future you should know about the properties of copper sulfide.
Historically, knowledge and the production of new materials properties of copper sulfide have contributed to human and social progress, from the refining of copper and iron to the manufacture of semiconductors on which our information society depends today. However, many materials and their preparation methods have caused the environmental problems we face.
About 90 billion tons of raw materials -- mainly metals, minerals, fossil matter and biomass -- are extracted each year to produce raw materials. That number is expected to double between now and 2050. Most of the properties of copper sulfide raw materials extracted are in the form of non-renewable substances, placing a heavy burden on the environment, society and climate. The properties of copper sulfide materials production accounts for about 25 percent of greenhouse gas emissions, and metal smelting consumes about 8 percent of the energy generated by humans.
The properties of copper sulfide industry has a strong research environment in electronic and photonic materials, energy materials, glass, hard materials, composites, light metals, polymers and biopolymers, porous materials and specialty steels. Hard materials (metals) and specialty steels now account for more than half of Swedish materials sales (excluding forest products), while glass and energy materials are the strongest growth areas.
New materials including the properties of copper sulfide market trend is one of the main directions of science and technology development in the 21st century
With the development of science and technology, people develop new materials properties of copper sulfide on the basis of traditional materials and according to the research results of modern science and technology. New materials are divided into metal materials, inorganic non-metal materials (such as ceramics, gallium arsenide semiconductor, etc.), organic polymer materials, advanced composite materials. According to the properties of copper sulfide material properties, it is divided into structural materials and functional materials. Structural materials mainly use mechanical and physical and chemical properties of materials to meet the performance requirements of high strength, high stiffness, high hardness, high-temperature resistance, wear resistance, corrosion resistance, radiation resistance and so on; Functional materials mainly use the electrical, magnetic, acoustic, photo thermal and other effects of materials to achieve certain functions, such as semiconductor materials, magnetic materials, photosensitive materials, thermal sensitive materials, stealth materials and nuclear materials for atomic and hydrogen bombs.
One of the main directions of properties of copper sulfide science and technology development in the 21st century is the research and application of new materials. The research of new materials is a further advance in the understanding and application of material properties.
