“…Additionally, the shift of the peaks from 1647 cm −1 to 1580 cm −1 in the case of OX-AIE may have been due to the interaction of oxazoline groups of OX with the nucleophilic sites in AIE PS. The bactericidal activity of the plasma-modified surfaces was evaluated using a live dead assay under dark conditions and after light exposure for 30 min and 1 h. S. aureus and P. aeruginosa were the typical Gram-positive and Gram-negative bacteria chosen for the study, as they are mostly found in contaminated hospital fabrics and are involved in the transmission of HAIs [26]. Figures 2 and 3 demonstrate that the viability of both S. aureus and P. aeruginosa was least affected on uncoated and OX-coated surfaces.…”

In the quest to curtail the spread of healthcare-associated infections, this work showcases the fabrication of a cutting-edge antibacterial textile coating armoured with aggregation-induced emission photosensitisers (AIE PS) to prevent bacterial colonisation on textiles. The adopted methodology includes a multi-step process using plasma polymerisation and subsequent integration of AIE PS on their surface. The antibacterial effectiveness of the coating was tested against Pseudomonas aeruginosa and Staphylococcus aureus after light irradiation for 1 h. Furthermore, antibacterial mechanistic studies revealed their ability to generate reactive oxygen species that can damage bacterial cell membrane integrity. The results of this investigation can be used to develop ground-breaking explanations for infection deterrence, principally in situations where hospital fabrics play a critical part in the transmission of diseases. The antibacterial coating for textiles developed in this study holds great promise as an efficient strategy to promote public health and reduce the danger of bacterial diseases through regular contact with fabrics.

“…bacterial genus to a diverse array of textile materials, a genus ubiquitous on human skin [1]. Among the pathogens recognized by the World Health Organization responsible for healthcare-associated infections is Staphylococcus aureus (S. aureus) [2]. Microorganism colonization on textile surfaces has detrimental effects, including health problems, disease transfer, cross-infections, unpleasant odors, and reduced textile quality due to diminished fiber strength [3,4].…”

In healthcare facilities, infections caused by Staphylococcus aureus (S. aureus) from textile materials are a cause for concern, and nanomaterials are one of the solutions; however, their impact on safety and biocompatibility with the human body must not be neglected. This study aimed to develop a novel multilayer coating with poly(allylamine hydrochloride) (PAH) and immobilized ZnO nanoparticles (ZnO NPs) to make efficient antibacterial and biocompatible cotton, polyester, and nylon textiles. For this purpose, the coated textiles were characterized with profilometry, contact angles, and electrokinetic analyzer measurements. The ZnO NPs on the textiles were analyzed by scanning electron microscopy and inductively coupled plasma mass spectrometry. The antibacterial tests were conducted with S. aureus and biocompatibility with immortalized human keratinocyte cells. The results demonstrated successful PAH/ZnO coating formation on the textiles, demonstrating weak hydrophobic properties. Furthermore, PAH multilayers caused complete ZnO NP immobilization on the coated textiles. All coated textiles showed strong growth inhibition (2−3-log reduction) in planktonic and adhered S. aureus cells. The bacterial viability was reduced by more than 99%. Cotton, due to its better ZnO NP adherence, demonstrated a slightly higher antibacterial performance than polyester and nylon. The coating procedure enables the binding of ZnO NPs in an amount (< 30 µg cm−2) that, after complete dissolution, is significantly below the concentration causing cytotoxicity (10 µg mL−1).

“…This correspondingly leads to the assimilation of microorganisms with films of water and their viability in the textiles become veritable channels for the transmission of infectious agents, including multidrug-resistant, MDR bacterial species [2][3][4]. The standard towel in the home or public arena has been recognized as being accountable for the transfer of pathogenic microorganisms in the home, healthcare institutions and within the community [5][6]. The realization that re-useable towels contribute to inadequate hand hygiene that is traceable to illnesses in developing countries is central to the drive for the elimination of the re-useable towel from restaurants and other public places [7] and replacement with hand dryers after hand washing [8].…”

Bath towels are designed to assimilate profuse amount of moisture and in the process may also absorb microorganisms that are present. These microorganisms remain viable and multiply within the moist towel to become vehicles for the transmission of infectious agents especially through contaminated hands to food, household items and the surrounding environment. The study was intended to know the level of bacterial colonization of bath towels of students in a tertiary educational institution in Owo, Ondo State. Students’ bath towels were swabbed with cotton wool-tipped swab sticks and teased into 5 mL sterile 0.85% sodium chloride. This was diluted ten-folds serially: 10-1 , 10-2 , 10-3 ... 10-10, and 0.1 mL each was inoculated onto standard bacteriological media. The cultures were incubated at 37oC overnight before reading. Bacterial counts increased significantly (p<0.05) from 3.4 x 104 in first week of laundry to 2.9 x 108 in towels laundered after three weeks of use. Staphylococcus aureus (74.3%) was the predominant isolate. Escherichia coli (20.2%) was the next frequently recovered microorganism. Other isolates were Klebsiella species (3.7%) and Pseudomonas aeruginosa (1.8%) was the least recovered organism. The isolates were most susceptible to pefloxacin, except Pseudomonas aeruginosa that had better susceptibility to gentamycin. The high level of bacterial colonization of bath towels with some of the regular microorganisms implicated in most human diseases brings to fore the urgent need for education on the basics of the bath towel hygiene.
