Porous and Nanomaterials
Recently, functional porous materials with hierarchically pore, are developed a range of novel techniques to fabricate aligned porous and hierarchically porous materials, and nanostructures. The great challenge that is to control the hierarchically meso-, macroporous materials with individual pore size, porous structures, and functionalities for various applications such as drug delivery, catalysis, chromatography etc.
Bioactive glasses (BGs)
Bioactive glasses (BGs) are compatible with human body, bond to bone and can stimulate new bone growth while dissolving overtime. In a relate project, we have synthesized three dimensionally ordered macroporous (3DOM) bioactive glasses directly synthesis by templating and self-assembly methods. Using polymer or surfactant templates we can control the architecture of porous and nanostructured materials and create products with special properties
BGs with hierarchically porous are investigated as a host for uptake and controlled release of drug components. Furthermore, the magnetic mesoporous bioactive glass (MMBG) has been interested because it possesses the multifunction including excellent biocompatibility, magnetic property, and mesoporous structure. It is possible to achieve the bonding of the bioactive glass and the bone and the growth of the latter. On the other hand, iron ions play an important role in the magnetic intracellular hyperthermia treatment of bone cancer
Hydroxy-/Fluoroapatite (HAp/FAp) is the most used materials in biomedical field due to their biocompatibility and bioactivity, can be synthesized via numerous production routes, using various different reactants. More effort, we have been focused into synthesis from less expensive raw materials such as eggshells, coral, mussel etc. and using low cost methods.
Hierarchical porous polymers
Hierarchical porous polymers possess large specific surface area, tunable surface function and high adsorption capacity. We have been synthesized and implemented as porous adsorbents for miniaturized sample preparation techniques of trace organic contaminants in environmental and food analysis. These hierarchically structured porous adsorbents represent a promising alternative to commercially packed cartridges.
Multifunctional composite adsorbent
The integration of porous materials with inherently different properties is applied as the hybrid composite adsorbent which facilitates highly efficient adsorption due to the combination of multifunctional adsorption affinity and larger surface area.
In our group, the multifunctional composite adsorbents are fabricated and used for miniaturized sample preparation and extraction devices for the application in environmental and food analysis.
Macroporous conducting carbon membrane
In our group the macroporous conducting carbon membrane was prepared via cryogelation, freeze-drying, and subsequent carbonization. The membrane prosses an interconnected 3D porous structure with continuous macropores. The structure is very attractive for applying as electrodes since it has unique monolithic structures, i.e., rich macroporosity and multi-dimensional electron transport pathways.
Nanomaterials for electrochemical sensors
Our team focuses on synthesis and characterizations of nano- and micro- materials for electrochemical sensors. The structure and type of materials were designed in a form of nanoparticle, nanorod, nanowire or thin film of metals, metal oxides, alloys and polymers.
