Applications of Nanocellulose/Nanocarbon Composites: Focus on Biotechnology and Medicine
Nanocellulose/nanocarbon composites are newly-emerging smart hybrid materials containing cellulose nanoparticles, such as nanofibrils and nanocrystals, and carbon nanoparticles, such as “classical” carbon allotropes (fullerenes, graphene, nanotubes and nanodiamonds), or other carbon nanostructures (carbon nanofibers, carbon quantum dots, activated carbon and carbon black). The nanocellulose component acts as a dispersing agent and homogeneously distribute the carbon nanoparticles in aqueous environment. Nanocellulose/nanocarbon composites can be prepared with many advantageous properties, such as high mechanical strength, flexibility, stretchability, tunable thermal and electrical conductivity, tunable optical transparency, photodynamic and photothermal activity, nanoporous character and high adsorption capacity. They are therefore promising for a wide range of industrial applications, such as energy generation, storage and conversion, water purification, food packaging, construction of fire retardants and shape memory devices. They also hold great promise for biomedical applications, such as radical scavenging, photodynamic and photothermal therapy of tumors and microbial infections, drug delivery, biosensorics, isolation of various biomolecules, electrical stimulation of damaged tissues (e.g. cardiac, neural), neural and bone tissue engineering, engineering of blood vessels and advanced wound dressing, e.g. with antimicrobial and antitumor activity. However, the potential cytotoxicity and immunogenicity of the composites and their components must also be taken into account.

Applications of Nanoparticles
In recent times, metal oxide nanoparticles (NPs) have been regarded as having important commercial utility. However, the potential toxicity of these nanomaterials has also been a crucial research concern. In this regard, an important solution for ensuring lower toxicity levels and thereby facilitating an unhindered application in human consumer products is the green synthesis of these particles. Although a naïve approach, the biological synthesis of metal oxide NPs using microorganisms and plant extracts opens up immense prospects for the production of biocompatible and cost-effective particles with potential applications in the healthcare sector.

Applications of Nanotechnology in Food & Cosmetics Preservation
Cosmetic and food products containing water are prone to contamination during the production, storage, and transit process, leading to product spoilage and degraded organoleptic characteristics. The efficient preservation of food and cosmetics is one of the most important issues the industry is facing today. The use of nanotechnology in food and cosmetics for preservation purposes offers the possibility to boost the activity of antimicrobial agents and/or promote their safer distribution into the end product upon incorporation into packaging or film constructions.

Applications of Piezoelectric Micro-Power Generators
Mechanical power is the most common type of external energy that can be converted into useful electric power. Because of its strong electromechanical coupling ability, the piezoelectric mechanism is a far more successful technique for converting mechanics energy to electrical energy when compared to electrostatic, electromagnetic, and triboelectric transduction systems. The scientific community has maintained a strong interest in piezoelectric micro-power generators because of their great potential for powering a sensor unit in the distributed network nodes. A national network usually has a large mass of sensor units distributed in each city, and a self-powered sensor network is eagerly required.

Applications of Poly(3-hydroxybutyrate-co-3-hydroxyvalerate)-Based Materials
Among the various biopolymers derived from the PHA family, the copolymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), commonly known as PHBV, stands out for its inherent versatility. Unlike many other members of the PHA family that are derived from a single monomer and exhibit consistent physicochemical properties, PHBV offers the unique advantage of tunability. By adjusting the ratio of 3HB to 3HV monomers, the material properties can be tailored to produce products from flexible films to rigid molded objects. This adaptability made PHBV more versatile and expanded its potential applications.
