An Oxygen‐Self‐Produced Nanoplatform Based on MnO2 for Relieving Hypoxia

ChemNanoMat (2024)

Guohua Pan Hanxiao Bao Jinguo Zhang Jue Hou Jun Zhou

Manganese dioxide ( MnO2) nanoparticles are increasingly recognized for their potential in biomedical applications, particularly in the realm of hypoxic cancer therapy, due to their unique physicochemical characteristics. This investigation introduces a novel, template‐free synthesis strategy. The reducing groups inherent in bovine serum albumin (BSA) facilitate a redox reaction with potassium permanganate (KMnO4), while the abundance of functional groups in BSA is instrumental in the formation of MnO2. The transmission electron microscopy (TEM) analysis has characterized the synthesized MnO2 nanoparticles, termed BM NPs, as spherical particles with a mean diameter of 210 nm and zeta potential of −40.1 mV measured by dynamic light scattering (DLS). The Fourier transform infrared (FT‐IR) spectrum of BM NPs exhibits the characteristic peak of MnO2 at 1113 cm‐1 and 620 cm‐1. Furthermore, the elemental composition of BM NPs has been ascertained through energy‐dispersive X‐ray (EDX) elemental mapping analysis. Though concentration of BM NPs up to 200 μg/mL, the survival rate of 4T1 cells remained approximately 75%. Given that BM NPs at a concentration of 100 µg/mL significantly alleviate cellular hypoxia, the high oxygen‐generating capacity of these nanoparticles is proved, suggesting their suitability as a drug delivery system, especially in the context of hypoxic tumor microenvironments.

Intercalation of Diverse Organic Guests into Layered Europium Hydroxides – Structural Tuning and Photoluminescence Behavior

European Journal of Inorganic Chemistry (2013)

Qingyang Gu Nankai Chu Guohua Pan Genban Sun Shulan Ma

Abstract Organic anions of two benzenepolycarboxylic acids [1,3,5‐benzenetricarboxylic acid (BTA) and 2,2′‐biphenyldicarboxylic acid (BDA)], two pyridinecarboxylic acids [quinolinic acid (QA) and 2,5‐pyridinedicarboxylic acid (PDA)], and two amino acids [phenylalanine (Phe) and tyrosine (Tyr)] were intercalated into the galleries of NO 3 – ‐type layered europium hydroxide (NO 3 –LEuH). All the prepared products displayed XRD patterns with series of diffractions due to layered materials. The composite structures and the arrangement of the guests in the galleries were investigated in detail. The structure of the organic guests (such as the number and position of carboxyl groups) affects the arrangement in the interlayer. SEM observations showed that the NO 3 –LEuH precursor and its intercalates crystallize in a columnar or layered stacking structure composed of hexagonal thin platelets. The luminescence study indicated that all samples display the typical red emission of Eu 3+ . Efficient energy transfer between intercalated BTA/BDA anions and Eu 3+ centers takes place, markedly enhancing the Eu 3+ luminescence, whereas QA–LEuH and PDA–LEuH with pyridinedicarboxylic acid anions show no obvious change in luminescence intensity. When amino acid anions such as Phe and Tyr were introduced into the interlayer, the Eu 3+ emission was strongly quenched. The simple soft chemical method can open great opportunities for developing organic–inorganic multifunctional luminescent materials or biological probes for detecting certain amino acids.
