Quercetin- and caffeic acid-functionalized chitosan-capped colloidal silver nanoparticles: one-pot synthesis, characterization, and anticancer and antibacterial activities
Beilstein J. Nanotechnol. 2023, 14, 362–376, doi:10.3762/bjnano.14.31
- characterization of quercetin- and caffeic acid-functionalized chitosan-capped colloidal silver nanoparticles (Ch/Q- and Ch/CA-Ag NPs), and their antibacterial and anticancer activities. The formation of Ch/Q- and Ch/CA-Ag NPs has been confirmed by ultraviolet–visible (UV–vis) spectroscopy, Fourier-transform
- infrared (FTIR) spectroscopy, and transmission electron microscopy (TEM). The characteristic surface plasmon resonance (SPR) absorption band has been found at 417 and 424 nm for Ch/Q- and Ch/CA-Ag NPs, respectively. The formation of a chitosan shell comprising quercetin and caffeic acid, which surround the
- (P. aeruginosa and E. coli) and Gram-positive (S. aureus and S. epidermidis) bacteria was determined, and dose-dependent antibacterial effects were found. Keywords: Ag NPs; anticancer and antibacterial effects; caffeic acid; chitosan; one-pot synthesis; quercetin; U-118 MG and ARPE-19 cells
Recent progress in cancer cell membrane-based nanoparticles for biomedical applications
Beilstein J. Nanotechnol. 2023, 14, 262–279, doi:10.3762/bjnano.14.24
- effectively increased in tumor tissues, and the side effects on normal tissues can be significantly reduced [92]. Quercetin (QT), a flavonoid with various functions, such as antitumor activity and radiosensitization, has been loaded into NPs and encapsulated by cancer cell membranes to further study its
Engineered titania nanomaterials in advanced clinical applications
Beilstein J. Nanotechnol. 2022, 13, 201–218, doi:10.3762/bjnano.13.15
- ]. Non-steroidal anti-inflammatory drugs (e.g., quercetin, ibuprofen, dexamethasone, aspirin, indomethacin) have been successfully loaded and eluted locally from TNTs in vitro in titania-based implants. Surface modifications such as biopolymer coating, polymeric micelle encapsulation, and periodic
A review on the green and sustainable synthesis of silver nanoparticles and one-dimensional silver nanostructures
Beilstein J. Nanotechnol. 2021, 12, 102–136, doi:10.3762/bjnano.12.9
- micelle method has served as a common approach for the synthesis of AgNPs throughout the past two decades [152]. Regular reducing agents used in this method include sodium borohydride (NaBH4) [236], hydrazine (N2H4) [237], glucose [238], and quercetin [152][239], to name a few. The size and size
Nanoconjugates of a calixresorcinarene derivative with methoxy poly(ethylene glycol) fragments for drug encapsulation

- nanoassociates that are able to encapsulate organic substrates of different hydrophobicity, including drugs (doxorubicin, naproxen, ibuprofen, quercetin). The micelles of the macrocycle slowed down the release of the hydrophilic substrates in vitro. In physiological sodium chloride solution and phosphate
- encapsulation of hydrophobic substrates The encapsulation of model compounds of different hydrophobicity by macrocycle 3 was studied (Table 2). These compounds were doxorubicin (Dox), an anthracycline antitumor antibiotic, quercetin (QC), a flavonol that exhibits decongestant, antispasmodic, antihistaminic
- , Orange OT, ibuprofen, naproxen sodium, naproxen were purchased from Sigma-Aldrich, rhodamine B was purchased from Acros. Quercetin and doxorubicin hydrochloride were kindly supplied by Prof. E. Kh. Kazakova. Doxorubicin hydrochloride was hydrophobized by the method reported in [37]. Tosylated mPEG-550 2
