Nano-Materials for Bioimaging

Highly surface functionalized carbon nano-onions for bright light bioimaging.

Carbon-based nanomaterials functionalized with fluorescent and water-soluble groups have emerged as platforms for biological imaging because of their low toxicity and ability to be internalized by cells. The development of imaging probes based on carbon nanomaterials for biomedical studies requires the understanding of their biological response as well as the efficient and safety exposition of ...

Nano-materials for Novel Magneto-Rheological Liquids and Nano-fluids

Nano Characterization of Materials

Material and device characterization is challenged by continuously decreasing device dimensions placing significant demands on characterization instruments and measurement interpretation. The trend in many techniques is clearly toward characterization of smaller dimensions. Among the myriad of characterization techniques in use today, I discuss recent advances in probe microscopy, interferometr...

Supramolecular quantum dots as biodegradable nano-probes for upconversion-enabled bioimaging.

We report the biodegradable supramolecular quantum dots (SQDs) of hydrogen-bonded graphitic carbon nitride (g-C3N4) with low cytotoxicity and desirable biocompatibility for promising upconversion-enabled fluorescent bio-probes. A remarkable biodegradation of up to 97% within 24 hours is presented.

Metal-organic framework materials as nano photocatalyst

Photocatalytic degradation of toxic organic compound in water, soil and air by semiconductor catalysts such as TiO2 and ZnO have received much attention over the last two decades. However, the low quantum yield, easy agglomeration and difficult post-separation of these inorganic catalysts limit their application for large-scale applications. Metal-organic frameworks (MOFs) are the latest class ...
