What are the Key Applications in Bioanalytical Sciences?
MNPs play a crucial role in several bioanalytical applications:
1. Magnetic Separation: MNPs are used to isolate specific biological entities such as cells, proteins, and nucleic acids. Functionalized MNPs can bind to target molecules and be separated using a magnetic field.
2. Biosensors: MNPs enhance the sensitivity and specificity of biosensors. They can be used in conjunction with various detection techniques such as electrochemical, optical, and magnetic detection.
3. Drug Delivery: MNPs can be engineered to deliver therapeutic agents to specific sites within the body, minimizing side effects and improving the efficacy of the treatment.
4. Imaging: MNPs are used as contrast agents in magnetic resonance imaging (MRI), providing higher resolution images. They can also be utilized in other imaging techniques like fluorescence microscopy.
