“…Another study evaluated phototherapy and antibacterial effects of polypyrrole modified CNTs on Pseudomonas aeruginosa. At the NIR field, polypyrrole modified CNTs increased the temperature and induced photokilling of P. aeruginosa compared to the dark field; the NIR field induces a 70% killing rate, ROS generation, protein and nucleic acid leakage from P. aeruginosa [107]. A long circulating SWCNT complex was fabricated by using a new SWCNT dispersion agent, i.e., Evans blue.…”

Current discoveries as well as research findings on various types of carbon nanostructures have inspired research into their utilization in a number of fields. These carbon nanostructures offer uses in pharmacy, medicine and different therapies. One such unique carbon nanostructure includes carbon nanotubes (CNTs), which are one-dimensional allotropes of carbon nanostructure that can have a length-to-diameter ratio greater than 1,000,000. After their discovery, CNTs have drawn extensive research attention due to their excellent material properties. Their physical, chemical and electronic properties are excellent and their composites provide great possibilities for enormous nanometer applications. The current study provides a systematic review based on prior literature review and data gathered from various sources. The various research studies from many research labs and organizations were systematically retrieved, collected, compiled and written. The entire collection and compilation of this review concluded the use of CNT approaches and their efficacy and safety for the treatment of various diseases such as brain tumors or cancer via nanotechnology-based drug delivery, phototherapy, gene therapy, antiviral therapy, antifungal therapy, antibacterial therapy and other biomedical applications. The current review covers diverse applications of CNTs in designing a range of targeted drug delivery systems and application for various therapies. It concludes with a discussion on how CNTs based medicines can expand in the future.

“…Thus, PPy/CNT nanocomposites show a good combination of conductivity, antibacterial activity, and strong absorption of light in the NIR region. Tondro et al [ 52 ] developed this type of nanocomposites and applied them in a phototherapy treatment based on IR light irradiation. The straight incidence of irradiation boosts the physical rupture of the cells by the CNTs, the electrostatic attraction of PPy to the bacterial cells, and the extra generation of ROS.…”

The development of novel approaches to prevent bacterial infection is essential for enhancing everyday life. Carbon nanomaterials display exceptional optical, thermal, and mechanical properties combined with antibacterial ones, which make them suitable for diverse fields, including biomedical and food applications. Nonetheless, their practical applications as antimicrobial agents have not been fully explored yet, owing to their relatively poor dispersibility, expensiveness, and scalability changes. To solve these issues, they can be integrated within polymeric matrices, which also exhibit antimicrobial activity in some cases. This review describes the state of the art in the antibacterial applications of polymeric nanocomposites reinforced with 0D fullerenes, 1D carbon nanotubes (CNTs), and 2D graphene (G) and its derivatives such as graphene oxide (GO) and reduced graphene oxide (rGO). Given that a large number of such nanocomposites are available, only the most illustrative examples are described, and their mechanisms of antimicrobial activity are discussed. Finally, some applications of these antimicrobial polymeric nanocomposites are reviewed.

“…A thin layer of PPy was deposited on filter membranes as the photothermal material to kill bacteria via irradiation of 4.5 sun solar light before they are driven out of the air purification device, and such PPy-coated filter membranes were demonstrated to be reusable and low cost. 68 Moreover, PPy was utilized to coat carbon nanotubes 69 and carbon NPs, 70 leading to the formation of carbon@polypyrrole nanotubes and carbon nanoparticle/polypyrrole nanocomposites, respectively. Both nanomaterials were capable of realizing the photothermal ablation of Pseudomonas aeruginosa (P. aeruginosa) with the NIR light irradiation.…”

Microbial infections pose major threats to human health, and such a situation is further exasperated by microbial resistance to conventional antibiotics. It is therefore highly imperative to develop antimicrobial agents or strategies to achieve effective microbicidal effects. Recently, conjugated polymers (CPs) have shown their capacity to serve as effective photothermal agents (PTAs) for antimicrobial photothermal therapy (PTT). In this review, we first introduce the latest advances in the development of CPs as PTAs for combating microbes. We focus on the most-investigated polydopamine (PDA)-based PTT for killing microorganisms, in which the PDA-based PTAs are mainly in the formulations of nanoparticles, hydrogels, and surface coatings. Meanwhile, we present antimicrobial PTT based on the other CPs, including polypyrrole, polyaniline, and poly (3,4-ethylenedioxythiophene). Finally, we discuss both the current limitations and future directions of the CP-derived antimicrobial PTT.
