Nanotechnology enhances biocompatibility through several approaches:
1. Surface Modification: The surface properties of nanomaterials can be tailored to improve their interaction with biological tissues. For instance, coating nanoparticles with biocompatible polymers or peptides can reduce toxicity and increase cellular uptake.
2. Size and Shape Control: The size and shape of nanodevices can be precisely controlled to optimize their interaction with cells and tissues. Spherical nanoparticles, for example, may have different uptake dynamics compared to rod-shaped ones.
3. Functionalization: Nanoparticles can be functionalized with specific molecules that target certain cells or tissues, improving their efficacy and reducing off-target effects. This is particularly useful in targeted drug delivery.
