“…Metal nanoparticles such as Ag and Cu are known for their ability to inhibit the growth of microorganisms due their highly antimicrobial effects . Thus, Ag, Cu, and Fe MNP‐loaded GA/HA‐M cryogel composites were prepared to enhance the killing effects of the bare GA/HA cryogel.…”

“…The hemocompatibility of GA/HA‐M cryogel composites was increased in the order of Ag < Cu < Fe NPs with blood clotting indexes of 22.2 ± 8.3, 27.3 ± 11.1, and 48.0 ± 8.3, respectively. According to the literature, green‐synthesized Ag, Cu, and Fe NPs can be used for in vivo biological applications with high hemocompatibility . These MNPs were loaded via the interaction of the functional groups of HA particles into the cryogel network, and the blood compatibility, especially antitrombogenic activity, was increased by the loadings of these MNPs into the structure.…”

“…Furthermore, HA is well known for adsorption of metal ions and stabilization agent for metal nanoparticles (MNPs) because of its high complexation affinity with metal species . Metal nanoparticles, such as Fe, Ag, and Cu NPs, can be introduced into the prepared GA/HA cryogels as GA/HA‐M (M: Fe, Ag, and Cu) cryogel composites that render increased antimicrobial activity for the resultant materials . Morphological and physicochemical characterizations of the particles and cryogels were evaluated by using scanning electron microscope (SEM), Fourier transform infrared (FT‐IR), dynamic light scattering (DLS), and zeta potential measurements.…”

Super porous gum Arabic (GA) cryogels were synthesized by crosslinking of natural GA with divinyl sulfone at cryogenic conditions, −20°C for potential biomedical applications. Humic acid (HA) nanoparticles were also prepared by using degradable and biocompatible crosslinkers such as trimethylolpropane triglycidyl ether, poly(ethylene glycol) diglycidyl ether, and trisodium trimetaphosphate in a single step and then entrapped within GA cryogel network as GA/HA particle cryogel. Furthermore, GA/HA cryogel was used as a template for Ag, Cu, and Fe nanoparticle preparation, and their antimicrobial properties were tested against Escherichia coli, Staphylococcus aureus, and Bacillus subtilis strains. The minimum inhibition concentration values of Ag and Cu nanoparticle-loaded GA/HA cryogel composites were determined as 10 mg mL −1. Furthermore, the blood compatibility tests such as hemolysis and blood clotting indexes were determined for GA cryogels and found to be more compatible with 0.08 ± 0.01% hemolysis and 89.4 ± 6.1 blood clotting values, whereas the hemolysis of the Ag, Cu, and Fe nanoparticle-loaded GA/HA Ag, Cu, and Fe metal nanoparticle cryogel composites decreased in the order of Fe > Cu > Ag nanoparticles.

“…reported the first attempt to use lignin‐capped copper nanocolorants for cell imaging . Copper nanoparticles are well known for their fluorescence to a certain degree, but the lower fluorescence intensity and awful dispersibility prevent their application in bioimaging . Lignin‐capped copper nanoparticles were capable of supporting cell division without any physical damage to A549 cells and improved the stability of fluorescence intensity in cell imaging .…”

Lignin, as the most abundant aromatic renewable biopolymer in nature, has long been regarded as waste and simply discarded from the pulp and paper industry. In recent years, with many breakthroughs in lignin chemistry, pretreatment, and processing techniques, a lot of the inherent bioactivities of lignin, including antioxidant activities, antimicrobial activities, biocompatibilities, optical properties, and metal‐ion chelating and redox activities, have been discovered and this has opened a new field not only for lignin‐based materials but also for biomaterials. In this Review, the biological activities of lignin and drug/gene delivery and bioimaging applications of various types of lignin‐based material are summarized. In addition, the challenges and limitations of lignin‐based materials encountered during the development of biomedical applications are also discussed.

“…Metal nanoparticles, particularly gold and silver ones, have been studied due to their properties such as plasmon resonance and large surface area, among others [1][2][3]. They have an excellent and promising potential use in biomedical applications [4], including bioimaging [5], thermal therapy [6], and drug delivery [7]. They have also been studied for their antimicrobial [8][9][10] and cytotoxic activities [11][12][13], with satisfying results.…”

Antifungal and Cytotoxic Evaluation of Photochemically Synthesized Heparin-Coated Gold and Silver Nanoparticles

Heparin-based silver nanoparticles (AgHep-NPs) and gold nanoparticles (AuHep-NPs) were produced by a photochemical method using silver nitrate and chloroauric acid as metal precursors and UV light at 254 nm. UV–Vis spectroscopy graphs showed absorption for AgHep-NPs and AuHep-NPs at 420 nm and 530 nm, respectively. TEM revealed a pseudospherical morphology and a small size, corresponding to 10–25 nm for AgHep-NPs and 1.5–7.5 nm for AuHep-NPs. Their antifungal activity against Candida albicans, Issatchenkia orientalis (Candida krusei), and Candida parapsilosis was assessed by the microdilution method. We show that AgHep-NPs were effective in decreasing fungus density, whereas AuHep-NPs were not. Additionally, the viability of human gingival fibroblasts was preserved by both nanoparticle types at a level above 80%, indicating a slight cytotoxicity. These results are potentially useful for applications of the described NPs mainly in dentistry and, to a lesser extent, in other biomedical areas.
