“…However, the potentialities of the present treatments and technologies have been exhausted. Traditional cellulosic materials are unsuited for the engineering of high‐performance products, such as electronics, energy storage devices, packaging, and innovative textiles . This outcome is caused by inadequate dimensional and thermal stability, variability in mechanical strength, poor compatibility with the hydrophobic materials, low chemical resistance, and the absence of electrical conductivity.…”

“…This approach allows remediating disadvantages such as the high hygroscopicity and preventing fungal and bacterial decay. Metal and metal oxide nanoparticles can impart electrical conductivity, photocatalytic and bacteriostatic activity, self‐cleaning ability, and hydrophobic character . This direction is fertile ground for developing fibers, paper, textile, and aerogels with properties and functional capacity not known before, which has caused profound interest as expressed in a dramatic increase in research now and around the world.…”

“…This integration is made for a number of reasons: to increase material thermal, mechanical and chemical stabilities, wear protection and durability, decrease friction or inhibit corrosion, to biomimic material of natural origin, and to improve biocompatibility, thus changing the overall physicochemical and biological properties . This methodology stands out conspicuously in the textile industry in which inorganic nanoparticles with their unique properties differ from those of bulk materials and endow fabrics with UV protection, self‐cleaning, bacteriostatic, water proofing, superhydrophobic, electroconducting, flame retarding, strengthening, and optical properties that were unknown before . Mineralized paper with imparted conductivity is another example of a growing field of engineering materials of novel types of electronic devices, such as electrodes for supercapacitors, batteries, transistors, and flexible screens .…”

Cellulose possesses excellent properties, but its performance characteristics do not satisfy human requirements completely, which has soured a constant effort to improve its features. Currently, cellulose is combined with inorganics in a process called mineralization that results in a novel type of materials referred to as bio-nanocomposites. There are many examples of mineralized tissues with superior properties in living nature. This circumstance gives us a reason to biomimic them by compounding biopolymers with inorganics. Here, the main mineralization techniques, properties, structure, functionality, and application of mineralized cellulose are the focus. Cellulose can be combined with inorganics through the vapor phase or by the methods of wet chemistry. Much attention has been paid to sol-gel chemistry, which is of first importance in cellulose mineralization. Inorganics can protect polysaccharides, regulate hydrophilicity-hydrophobicity, and impart self-cleaning, antimicrobial and conducting properties, which not only improves them but results in bio-nanocomposites with novel functionalities and performance, not known before for cellulosic materials. Further calcination and carbonization of mineralized cellulose under mild conditions give nanosized metals, metal oxides, and their nanocomposites with carbon, which are often unavailable by conventional methods. Therefore, mineralization is used to develop innovative textiles, oil absorbent and oil/water separating membranes, catalysts and photocatalysts, solar cells, conductors, supercapacitors, transistors and batteries for flexible electronics, and energy storage devices. These nontraditional and highly promising areas for applications have caused an intense interest in cellulose that resembles its rediscovery.

Nanocząstki metali w wodach powierzchniowych -zagrożenie dla organizmów wodnychABSTRACT Purpose: The aim of this paper is to provide information on the risks posed by metal nanoparticles released into surface waters. Introduction: Currently, the use of nanoparticles of metal and metal oxides (NPMOs) is extremely popular in various industries, and in medicine and households. Nanoparticles and nanocompounds have become significant contributors to technological progress due to their physicochemical properties such as the melting point, electrical and thermal conductivity, catalytic activity, light absorption and scattering, as well as biocompatible and bactericidal properties. These functions cause their increased performance compared to their macro counterparts. However, it should be noted that the properties of nanocomponents can create new risks to the environment and consumers. Based on existing literature, a conclusion can be drawn that metal nanoparticles are a potential threat to plant and animal organisms, and humans. It is, therefore, necessary to intensify efforts to understand the mobility, reactivity and durability of nanocomponents in various environmental components, especially in the aquatic environment, and their toxicity to organisms. Methodology: This paper is a literature review. Conclusions:The increasing use of nanosubstances, in both commercial and industrial products, has caused an increasing concentration and diversity of these substances in aquatic ecosystems. Based on the analysis of literature reports, it can be concluded that the size of nanoparticles, their structure and arrangement, as well as surface properties, are subject to constant changes in the environment as a result of their interactions with other components, and of the balances shaped by a variety of geochemical and biological factors. Numerous studies conducted in recent years in the field of nanoecotoxicology have demonstrated the existence of a risk to aquatic organisms, which could lead to their impaired development and even death. Unfortunately, the lack of a standard technique for assessing the toxicity of nanoparticles in various biological systems, such as the reproductive, respiratory, nervous and gastrointestinal systems, and the developmental stages of aquatic organisms, makes it impossible to conduct such studies in a standardised fashion. Reports of the toxicity of metal and metal oxide nanoparticles in relation to various forms of living organisms warrant in-depth investigations into how these particles function in aqueous solutions and interact with standard substances.
