One of the major components of nanotechnology is Carbon nanotube (CNT) that can have a lengthto-diameter ratio more than 1,000,000. They are used in several fields in material science, due to their exceptional electrical, mechanical, and thermal properties, which are anisotropic. Different techniques have been developed to produce CNT. They have good potential for applications in various technological areas such as nanoelectronic, biotechnology, material science, polymer, composite, and textile industries. In this paper, recent researches on application of CNT in textile industry are reviewed. Treatment of textiles with CNT leads to the production of a wide variety of conductive textiles with different electrical properties. The wear performances of fabrics apply with CNT to open the potentiality of producing composite materials for conventional and innovative applications, ranging from conventional apparel and sportswear to protective clothing, heating equipment, automotive textiles, building covering, geo-textiles, biomedical textiles, etc.

“…In addition, CNTs have also been viewed as a potential nanofiller with an AF capacity (Beigbeder et al 2008;. Many studies have focused on the AF performance of CNTs on bacteria in laboratory bioassays (Kang et al 2007;Brady-Estévez et al 2008;Huggett et al 2009;Dong & Yang 2014;Yazhini & Prabu 2015). For example, Kang et al (2007) showed CNTs exhibited good efficacy for reducing the viability of Escherichia coli.…”

This study investigated the effect of carbon nanotubes (CNTs) and titanium dioxide (TiO2) incorporated in PDMS on biofilm formation and plantigrade settlement of Mytilus coruscus. TiO2 increased bacterial density, and CNTs also increased bacterial density but reduced diatom density in biofilms after 28 days. Further analysis was conducted between bacterial communities on glass, PDMS, CNTs (0.5 wt%) and TiO2 (7.5 wt%). ANOSIM analysis revealed significant differences (R > 0.9) between seven, 14, 21 and 28 day-old bacterial communities. MiSeq sequencing showed that CNTs and TiO2 impacted the composition of 28 day-old bacterial communities by increasing the abundance of Proteobacteria and decreasing the abundance of Bacteroidetes. The maximum decreased settlement rate in 28 day-old biofilms on CNTs and TiO2 was > 50% in comparison to those on glass and PDMS. Thus, CNTs and TiO2 incorporated in PDMS altered the biomass and community composition of biofilms, and subsequently decreased mussel settlement.

“…Particularly, fabrics bearing antibacterial properties can offer synergistic and dual beneficial effects to the textiles. [40][41][42][43][44] Nanoparticles amalgamated with modified cotton fabrics, conferred an extensive antibacterial activity and well-balanced laundering durability. 45 This is principally mediated through the binding of MNPs into the surface of the fabrics by forming electrostatic forces or coordinating interactions between MNPs and co-ordinating groups.…”

Background: A diabetic ulcer is one of the major causes of illness among diabetic patients that involves severe and intractable complications associated with diabetic wounds. Hence, a suitable wound-healing agent is urgently needed at this juncture. Greener nanotechnology is a very promising and emerging technology currently employed for the development of alternative medicines. Plant-mediated synthesis of metal nanoparticles has been intensively investigated and regarded as an alternative strategy for overcoming various diseases and their secondary complications like microbial infections. Hence, we are interested in developing phyto-engineered gold nanoparticles as useful therapeutic agents for the treatment of infectious diseases and wounds effectively. Methods and Results: We have synthesized phyto-engineered gold nanoparticles from the aqueous extract of Acalypha indica and characterized using advanced bio-analytical techniques. The surface plasmon resonance feature and crystalline behavior of gold nanoparticles were revealed by ultraviolet-visible spectroscopy and X-ray diffraction, respectively. High-performance liquid chromatography analysis of the extract demonstrated the presence of different constituents, while major functional groups were interpreted by the Fourier-transform infrared spectroscopy as the various stretching vibrations appeared for important O-H (3443 cm −1), C=O (1644 cm −1) and CO (1395 cm −1) groups. Scanning electron microscopy, high-resolution transmission electron microscopy results revealed a distribution of spherical and rod-like nanostructures with 20 nm of size. The gold nanoparticle-coated cotton fabric was evaluated for the antibacterial activity against Staphylococcus epidermidis and Escherichia coli bacterial strains which revealed remarkable inhibition at the zone of inhibition of 31 mm diameter against S. epidermidis. Further, antioxidant activity was tested for their free radical scavenging property, and the maximum antioxidant activity of the extract containing gold nanoparticles was found to be 80% at 100 µg/mL. The potent free radical scavenging property of the nanoparticles is observed at IC 50 value 16.25 µg/mL. Moreover, in vivo wound-healing activity was carried out using BALB/c mice model with infected diabetic wounds and observed the stained microscopic images at different time intervals (day 2, day 7 and day 15). It was noted that in 15 days, the wound area is completely re-epithelialized due to the presence of different morphologies such as spherical, needle and triangle nanoparticles. The reepithelialization layer is fully covered by nanoparticles on the wound area and also collagen filled in the scar tissue when compared with the control group. Conclusion: The pharmacological evaluation results of the study indicated an encouraging antibacterial and antioxidant activity of the greener synthesized gold nanoparticles tethered with aqueous extract of Acalypha indica. Moreover, we demonstrated enhanced in vivo wound-healing efficiency of the synthesized gold nano...
