δ-phase Manganese Dioxide Nanoplatelets Dispersions (MnO₂)

Product Overview

δ-phase Manganese Dioxide (MnO₂) with a unique flower-like structure is a specialized manganese oxide material that exhibits a three-dimensional petal arrangement. This structure effectively prevents the aggregation of nanoplatelets, offering a high surface area and excellent biocompatibility. Under mildly acidic conditions, δ-phase MnO₂ reacts with glutathione (GSH), a metabolic product of cancer cells, leading to the generation of Mn²⁺ and serving as a contrast agent for magnetic resonance imaging (MRI). Additionally, δ-phase MnO₂ acts as a catalyst in tumor treatment by decomposing hydrogen peroxide and releasing oxygen, which alleviates hypoxic conditions within tumors.

Key Features

• Crystal Structure: The δ-phase MnO₂ features a 2D layered nanostructure with a low cost and high surface area, contributing to superior performance in various applications.
• Electrochemical Performance: Its unique crystal structure endows δ-phase MnO₂ with excellent capacitive properties and good cycle stability, making it suitable for use in supercapacitors and batteries.
