Exploring the Synergy between Nano-Formulated Linezolid and Polymyxin B as a Gram-Negative Effective Antibiotic Delivery System Based on Mesoporous Silica Nanoparticles
Autor: Ismael Otri, Serena Medaglia, Ramón Martínez-Máñez, Elena Aznar, Félix Sancenón
Publikováno v: Nanomaterials, Vol 14, Iss 2, p 228 (2024)
Antimicrobial resistance is a current silent pandemic that needs new types of antimicrobial agents different from the classic antibiotics that are known to lose efficiency over time. Encapsulation of antibiotics inside nano-delivery systems could be

Fluorogenic Detection of Human Serum Albumin Using Curcumin-Capped Mesoporous Silica Nanoparticles
Autor: Ismael Otri, Serena Medaglia, Elena Aznar, Félix Sancenón, Ramón Martínez-Máñez
Publikováno v: Molecules, Vol 27, Iss 3, p 1133 (2022)
Mesoporous silica nanoparticles loaded with rhodamine B and capped with curcumin are used for the selective and sensitive fluorogenic detection of human serum albumin (HSA). The sensing mesoporous silica nanoparticles are loaded with rhodamine B, dec
