“…The different types of agar-based BNC films were synthesized by blending agar and six different copper nanoparticles (CuNPs). These agar bio-nanocomposite films were used as antibacterial agent against both Gram-positive and Gram-negative foodborne pathogenic bacteria (Shankar et al 2014). Armentano et al (2014) studied polymeric nanocomposites and surface-engineered materials and antimicrobial modifications of polymers using a nanocomposite approach.…”

SummaryWith the rise in human population across the globe especially in developing countries, the incidence of microbial infections are increasing with greater pace. On the other hand, available medication and therapies are found to be insufficient for the complete cure of such microbial infections due to the development of resistance against various antibiotics. Therefore, to cope up the menace of microbial infections and drug resistance, there is demand for new and compelling technology, which has the ability to impede these problems. Many research groups worldwide are finding a ray of hope in nanomaterials owing to their unique properties. In the present review we have discussed the reasons behind the development of new materials based on nanotechnology. It is mainly focused on pioneering studies on application of nanomaterials like carbon nanotube, fullerene, dendrimers, nanocomposite and metal nanoparticles in combating dreadful pathogens. Moreover, the concerns about their toxicity have also been discussed.

“…In this sense the incorporation of biocide agents could be an excellent strategy to provide the ability to inhibit bacterial growth. It is known that metallic particles like silver and copper have an antimicrobial action and are effective against a broad spectrum of bacteria, Cu nanocomposites have been used for intrauterine devices [7] and biocidal polymers [8], however these nanoparticles are also toxic when exposed to human cells [9,10]. Some studies have shown that SH-SY5Y human neuroblastoma cells are sensitive to the toxic effect of copper, associated to the production of reactive oxygen species [11].…”

In this study, an antibacterial, but not cytotoxic nanomaterial based on polyethylene and copper nanoparticles was prepared by in situ polymerization. PE-CuNps nanocomposites against Escherichia coli, completely suppressed the number of live bacteria after 12 h incubation compared to neat PE. TEM images showed that nanocomposites damage the plasma membrane of the bacteria, revealing a bacteriolytic effect. Toxic effects of copper nanoparticles on viability of neuroblastoma line cell also was evaluated, revealing a non cytotoxic effect for the doses used, showing that this nanocomposite is a ideal material for medical devices.

“…Agar has been used to form composite films with various biopolymers such as carrageenan and konjac glucomannan (Rhim & Wang, 2013), and gelatin (Gimenez et al, 2013) to improve physical and mechanical properties of the films. It has also been used as a carrier or matrix of antimicrobial materials such as grapefruit seed extract (Kanmani & Rhim, 2014), silver nanoparticles (Rhim, Wang, Lee, & Hong, 2014), copper nanoparticles (Shankar, Teng, & Rhim, 2014), and clay (Rhim, 2011). Cellulose nanocrystals have been used to improve mechanical and gas barrier properties of agar-based films (Reddy & Rhim, 2014).…”
