Antimicrobial activity of Novel spinel nanoferrites against pathogenic fungi and bacteria

Influence of Elastic and Optical Properties on AgFeO2 and AgCrO2 Delafossite to be Applied in High-Frequency Applications

“…Recently, ABO 2 delafossite-oxides [A is monovalent = silver (Ag), B is trivalent = chromium (Cr) or iron (Fe)] have been paid great attention due to several potential applications, such as water purification, conductors, antimicrobials, chemical sensors, and solar cells. [1][2][3][4][5][6][7][8][9][10][11] Moreover, it is known that silver (Ag) nanoparticles has high resistance against oxidation and high thermal and electrical conductivity that can be used in a wide range of useful applications. [12][13][14][15][16][17][18][19][20] In this work, the study of elastic properties and high-frequency applications is discussed for the first time for AgCrO 2 and AgFeO 2 delafossite; there is no previous literature on this subject.…”

Nanomaterial-Based Antifungal Therapies to Combat Fungal Diseases Aspergillosis, Coccidioidomycosis, Mucormycosis, and Candidiasis

“…Because of this, the molecules/organisms used to control particle dimensions and self-organization is very important. Sayed et al [94] synthesized two novel spinel nanoferrites (Ag 2 Fe 2 O 4 and Ag 2 Cr 2 O 4 ) by flash auto-combustion to test their antifungal activity against four Aspergillus species. At a 100 mg/mL concentration compared with fluconazole, Ag 2 Fe 2 O 2 nanoferrite exhibited 1-, 0.8-, and 0.9-times lower inhibition zones against A. flavus, A. fumigatus, and A. niger, respectively.…”

Evaluation of antimicrobial properties of a novel synthesized nanometric delafossite

“…The physical, structural, and magnetic properties of most of the investigated nanometric delafossite were reported in previous literatures in details [25,27,28,[32][33][34]. Crystallite and particle sizes were obtained by using field emission scanning electron microscopy (FESEM) and atomic force microscopy (AFM) ( Table 7).…”

“…Finally, novel synthesized nanometric delafossite are of the general formula ABO 2 , where A is a monovalent metal ions and B is a trivalent metal ions. Doping silver nanoparticles to form important compounds that can be applied in many fields as magnetic targeting, separators, cancer diagnosis, antimicrobial activities, water treatment, and biomedical applications [19][20][21][22][23][24][25][26][27]. The combination of the monovalent silver nanoparticles and the trivalent chromium, iron, or aluminum ions has many applications, especially as antimicrobial compounds [28][29][30][31][32][33][34][35][36].…”
