“…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...

“…In the last years researchers have strongly focused their efforts in the development of antibacterial and antimicrobial materials. Although the study of antimicrobial field dates back about one hundred years, the design of polymeric systems able to exhibit efficient inhibition of bacterial infections is a discussed and thriving technology, that has become pivotal not only in biological fields, hospital and healthcare environments, but also in laboratory, marine and some industrial applications [1][2][3][4]. The direct use of antibiotic agents could be the approach to counteract many infections, but the main constraints are related to the potential environmental toxicity, the bacterial resistance, the shortterm antimicrobial activity and the proteolytic instability and degradation [5,6].…”

The antimicrobial activity represents a cornerstone in the development of biomaterials: it is a leading request in many areas, including biology, medicine, environment and industry. Over the years, different polymeric scaffolds are proposed as solutions, based on the encapsulation of metal ions/particles, antibacterial agents or antibiotics. However, the compliance with the biocompatibility criteria and the concentration of the active principles to avoid under-and over-dosing are being debated. In this work, we propose the synthesis of a versatile hydrogel using branched polyacrylic acid (carbomer 974P) and aliphatic polyetherdiamine (elastamine®) through physico-chemical transition, able to show its ability to counteract the bacterial growth and infections thanks to the polymers used, that are not subjected to further chemical modifications. In particular, the antimicrobial activity is clearly demonstrated against Staphyloccoccus aureus and Candida albicans, two well-known opportunistic pathogens. Moreover, we discuss the hydrogel use as drug carrier to design a unique device able to combine the antibacterial/antimicrobial properties to the controlled drug delivery, as a promising tool for a wide range of biomedical applications.

“…[7][8][9][10][11][12][13] Fenton and Fenton-like treatments are best due to their high degradation ability, range of applicability and cost-effectiveness. [14][15][16][17] However, homogeneous Fenton-like degradation processes containing free reagents (iron ions and hydrogen peroxide) have some critical disadvantages, which is unacceptable for commercial applications such as selective reaction conditions (acidic pH), generation of iron sludge and single-use reagent is a costly and counterproductive procedure. Therefore, much effort has been invested to improve the treatment efficiency of the Fenton reaction process as well as extending their working conditions and cutting down on secondary pollution.…”
