Abstract
Aim: Quorum sensing (QS) is a density-dependent chemical process of cell-to-cell communication in which certain signals are activated, leading to the coordination of pathogenic behaviors and the regulation of virulence in bacteria. Inhibition of QS can prevent biofilm formation and reduce virulence behaviors of bacteria. Herein, bovine serum albumin (BSA)-coated silver nanoparticles (NPs) (Ag-Ag2S@BSA NPs) were synthesized and studied as an anti-QS agent. Materials & methods: Ag-Ag2S NPs prepared through a BSA-mediated biomineralization process under ambient aqueous conditions and their physicochemical properties were characterized. The anti-QS activity of the resulting BSA-coated NPs (Ag-Ag2S@BSA NPs) was investigated for the first time. Results & conclusion: The result confirmed the potential of Ag-Ag2S@BSA NPs as novel and useful therapeutic tools for antibacterial purposes.

Abstract
This work aimed to develop biocompatible non-leachable antimicrobial polymers without ionic structures. A series of nonionic hyperbranched polymers (HBPs) with an isatin-based backbone and phenolic terminal units were synthesized and characterized. The molecular structures and thermal properties of the obtained HBPs were characterized by SEC, NMR, FTIR, TGA and DSC analyses. Disk diffusion assay revealed significant antibacterial activity of the obtained phenolic HBPs against nine different pathogenic bacteria. The presence of a methoxy or long alkyl group close to the phenolic unit enhanced the antibacterial effect against certain Gram positive and negative bacteria. The obtained nonionic HBPs were blended in polyester poly(hexamethylene terephthalate) films, which showed no noticeable leakage after being immersed in water for 5 days. Finally, these HBPs showed no cytotoxicity effect to MG-63 osteoblast-like human cells according to MTT analysis, and negligible hemolytic effect.

Pullulan (Pull) decorated with monodisperse
Ag and Au nanoparticles
(NPs) was synthesized by a simple and green method. Samples were characterized
by FTIR, UV–vis, NMR, XRD, TGA, SEM, XPS, DLS, and TEM. SEM
images showed highly oriented microforms reported for the first time
for Pull, because of the supramolecular self-assembling behavior of
Pull chains. Antimicrobial and quorum sensing (QS) inhibition activities
were tested against six pathogen bacteria and reporter and biomonitor
strain. Pull decorated with NPs, in particular, Ag-modified ones,
outperformed pristine Pull. The cell proliferation was tested with
an MTT assay. NPs-decorated Pull was studied for the first time as
an inhibitory agent against bacterial signal molecules and found to
be a good candidate. The promising performance of AgNPs@Pull compared
to the commercial antibiotic gentamicin showed that it has great potential
as a therapeutic approach to overcome the bacterial resistance that
has developed against conventional antibiotics.

Abstract
![]()
Most macromolecular
antimicrobials are ionic and thus lack miscibility/compatibility
with nonionic substrate materials. In this context, nonionic hyperbranched
polyesters (HBPs) with indole or isatin functionality were rationally
designed, synthesized, and characterized. Antimicrobial disk diffusion
assay indicated that these HBPs showed significant antibacterial activity
against 8 human pathogenic bacteria compared to small molecules with
indole or isatin groups. According to DSC measurements, up to 20%
indole-based HBP is miscible with biodegradable polyesters (polyhydroxybutyrate
or polycaprolactone), which can be attributed to the favorable hydrogen
bonding between the N–H moiety of indole and the C=O
of polyesters. HBPs with isatin or methylindole were completely immiscible
with the same matrices. None of the HBPs leaked out from plastic matrix
after being immersed in water for 5 days. The incorporation of indole
into HBPs as well as small molecules facilitated their enzymatic degradation
with PETase from Ideonella sakaiensis, while isatin
had a complex impact. Molecular docking simulations of monomeric molecules
with PETase revealed different orientations of the molecules at the
active site due to the presence of indole or isatin groups, which
could be related to the observed different enzymatic degradation behavior.
Finally, biocompatibility analysis with a mammalian cell line showed
the negligible cytotoxic effect of the fabricated HBPs.

Abstract
Chitosan is an indispensable biopolymer for use as a drug carrier thanks to its non-toxic, biodegradable, biocompatible, antimicrobial, and anti-oxidative nature. In previous studies, chitosan was first dissolved into weak acids and formed into gel, then used for carrying pharmaceutically active compounds such as nanoparticles, capsules, composites, and films. Using the produced chitosan gel after dissolving it in weak acids has advantages, such as ease of processing for loading the required amount of active substance and making the desired shape and size. However, dissolved chitosan loses some of its natural properties such as fibrous structure, crystallinity, and thermal stability. In this study, for the first time, three-dimensional chitosan lenses obtained from an insect's (Tabanus bovinus) compound eyes, with the original shape intact, were tested as a drug carrier. A model drug, quercetin, was loaded into chitosan membrane, and its release profile was examined. Also, a point-of-care test was conducted for both chitin and chitosan membranes. Chitin and chitosan membranes obtained from insect corneal lenses were characterized by using FTIR, TGA, elemental analysis, and surface wettability analysis as well as stereo, binocular, and scanning electron microscopies. It was observed that chitosan membrane could be used as a drug carrier material. Both chitin and chitosan membranes will be improved for lateral flow assay, and these membranes can be tested for other bioengineering applications in further studies.

Abstract
The solvent extraction of metal picrates such as Ni2+, Cu2+, Co2+, Pb2+ and Cd2+ from the aqueous to the organic phase was studied using 2-(diphenylphosphino)aminopyridine (Ph2PNHpy). The effects of parameters including the pH of the aqueous phase and the ligand solution volume were investigated to determine the extraction ability of the ligand for metal ions. The results showed that the extraction percentages of metal ions were high at low pH values. The antibacterial activity of the aminophosphine was also screened against Escherichia coli (E. coli) ATCC 25922, Staphylococcus aureus (S. aureus) ATCC 25923, Pseudomonas syringae pv. tomato (P. syringae) DC300, Salmonella enterica serotype Typhmurium (S. typhmurium) SL 1344 and Streptococcus mutans (S. mutans) ATCC 25175. From the studies of antibacterial activity, it was observed that the ligand exhibited a potent inhibitory effect against all Gram-negative and Gram-positive bacteria with a diameter of inhibition zone ranging from 3.86 to 18.10 mm. The aminophosphine ligand (Ph2PNHpy) should be considered as a suitable bio-active molecule for antimicrobial material design and next-generation, non-toxic drug fabrication. The Ph2PNHpy obtained may have the potential for use as an antimicrobial additive for bioengineering applications.

Abstract
The growing interest in substituting synthetic products coming from non-renewable sources with products from biomass has focused attention on the lignin biopolymer. Its high availability, low price and properties make the development of new and valuable uses for lignin interesting, thus improving the economic and environmental aspects of the biomass conversion. To achieve this objective, the potential use of industrial kraft and organosolv lignins as antioxidants, antimicrobials and sunscreen products has been evaluated. The results of a detailed antibacterial and antifungal study demonstrated the high potential of kraft lignins against a variety of foodborne and human pathogenic microorganisms. Moreover, both organosolv and kraft lignins presented an effective protection factor (SPF values from 10–20), demonstrating their effectiveness as natural additives for the sun lotion market. In addition, lignin samples presented high antioxidant capacity compared to butylated hydroxytoluene (BHT), one common commercial antioxidant industrially used. Therefore, the development of innovative applications of lignins as a commodity for the chemical, pharmaceutical or cosmetic industries could expand their possible uses in the market giving new added values to lignin. New opportunities for industrial and lab-scale isolated lignin as an antioxidant, antimicrobial and sunscreen product.![]()
