Applications

Key MaterialsDescriptions
Cancer Imaging and DiagnosticsNanoparticles are being used to develop advanced imaging agents that can detect tumors with high sensitivity and specificity. For example, C dots have been used in positron emission tomography (PET) and optical imaging to monitor cancer progression and response to treatment.
Drug Delivery SystemsNanoparticles can serve as carriers for drugs, delivering them directly to diseased cells while minimizing exposure to healthy tissues. This approach is particularly valuable in cancer therapy, where precision is key to reducing side effects.
Point-of-Care DiagnosticsThe miniaturization of diagnostic devices has enabled the development of portable systems that can perform rapid tests using nanoparticles. These systems are ideal for point-of-care settings, such as clinics or home healthcare, where quick and accurate results are essential.

Our Advantages

High Sensitivity and Specificity

Nanoparticles can be engineered to bind to specific biomarkers, enabling the detection of diseases at very early stages. Their small size and surface functionality allow for precise targeting, which is critical in diagnostics.

Biocompatibility

Advances in nanoparticle design have led to the development of materials with improved biocompatibility and reduced toxicity. PEGylation has been shown to enhance the clearance of nanoparticles from the body, reducing the risk of adverse reactions

Multiplexing Capabilities

Nanoparticles can be designed to carry multiple diagnostic agents simultaneously, allowing for the simultaneous detection of multiple analytes. This is particularly useful in complex diseases where multiple biomarkers may be involved.
