“…Antimicrobial polymer is a range of agents with bacteria or fungi inhibition ability, which has been used widely in plastic, , textile, − water purification, and so on. Most of antimicrobial polymers bear cationic groups along polymer chains, thus facilitating the adsorption of the polymer onto bacteria surfaces and further inhibiting the growth of bacteria via various mechanisms. − As one of the cationic antimicrobial polymers, the guanidine-based polymer has attracted substantial interests due to its wide spectrum antimicrobial activity, excellent biocide efficiency and nontoxicity. − Guanidine polymer is usually synthesized by polycondensation between guanidinium and diamine, and often reckoned as an oligomer because of its low molecular weight (as low as 1000) .…”

Modified guanidine-based polymers with chain extension were synthesized by condensation and cross-linking polymerizations in an attempt to increase molecular weight and charge density of the antimicrobial polymers. The antimicrobial activity and the corresponding mechanisms were investigated by several approaches. The results indicated that the antimicrobial activities of the modified guanidine-based polymer, based on the minimum inhibition concentration (MIC) against E.coli, varied with alkyl monomer ratios. UV absorption at 260 nm further quantified the amount of intracellular components leaked into bacteria suspension. The UV absorption measurements were also used to monitor inhibition processes dynamically. It was found that the modified guanidine-based polymer inhibited the growth of bacteria by causing membrane compromised and intracellular leaked. Dual fluorescent dyes were used to stain all bacteria including the dead ones, which enabled us to utilize CLSM to visualize the viability of bacteria in the presence of various modified guanidine-based polymers without causing any damage. The morphologies of bacteria untreated and treated with modified guanidine-based polymer were observed using an atomic force microscope (AFM), which further demonstrated the damage of E.coli membrane and the leakage of intracellular component induced by the modified guanidine-based polymers.

“…It was noticed that there is correlation between the extent of exhaustion and zone of inhibition (ZOI). No sig- nificant difference was observed between ZOI of unwashed samples and five times washed samples, as illustrated in Table 17, which gives an indication that there is strong interaction between doxymycin and carboyxlate anion on the polymer which confers such durable antimicrobial function [65].…”

Demand for antimicrobial fabrics has grown significantly in recent years because of public awareness of the potential threat of spreading diseases and there will be an increasing role for medical textiles in the future world market. The number of applications of polymeric materials for medical purposes is growing very fast. Polymers have found applications in such diverse biomedical fields as tissue engineering, implantation of medical devices and artificial organs, prostheses, ophthalmology, dentistry, bone repair and many other medical fields. Polymer-based delivery systems enable controlled release of drugs into the body. The aim of the present review is to clarify the antimicrobial agents and their mechanism of action, test methods, and the recent developments in antimicrobial functional finishing of synthetic fibers for medical applications (commercially available bioactive fibers).

Developing special textiles (for patients in hospitals for example) properties, special antimicrobial and anticancer, was the main objective of the current work. The developed textiles were produced after dyeing by the novel formula of natural (non-environmental toxic) pigments (melanin amended by microbial-AgNPs). Streptomyces torulosus isolate OSh10 with accession number KX753680.1 was selected as a superior producer for brown natural pigment. By optimization processes, some different pigment colors were observed after growing the tested strain on the 3 media. Dextrose and malt extract enhanced the bacteria to produce a reddish-black color. However, glycerol as the main carbon source and NaNO3 and asparagine as a nitrogen source were noted as the best for the production of brown pigment. In another case, starch as a polysaccharide was the best carbon for the production of deep green pigment. Peptone and NaNO3 are the best nitrogen sources for the production of deep green pigment. Microbial-AgNPs were produced by Fusarium oxysporum with a size of 7–21 nm, and the shape was spherical. These nanoparticles were used to produce pigments-nanocomposite to improve their promising properties. The antimicrobial of nanoparticles and textiles dyeing by nanocomposites was recorded against multidrug-resistant pathogens. The new nanocomposite improved pigments' dyeing action and textile properties. The produced textiles had anticancer activity against skin cancer cells with non-cytotoxicity detectable action against normal skin cells. The obtained results indicate to application of these textiles in hospital patients’ clothes.
