Long term tracking in
nanotechnology refers to the continuous monitoring and recording of the behavior, location, and interaction of
nanoparticles or nanodevices over an extended period. This process is crucial for understanding the
biocompatibility,
toxicity, and overall performance of nanomaterials within various environments, including biological systems.
The ability to track nanoparticles over long durations is essential for several reasons:
Safety and Toxicology: Continuous monitoring helps in assessing the long-term
toxicological effects of nanoparticles, ensuring they are safe for human and environmental health.
Drug Delivery: In
targeted drug delivery, tracking ensures that the therapeutic agents reach the desired location and release their payload over the intended timeframe.
Environmental Impact: Understanding the environmental behavior of nanoparticles helps in evaluating their impact and devising strategies for
sustainability.
Several advanced techniques are employed to achieve long term tracking in nanotechnology:
Challenges in Long Term Tracking
Despite the advancements, there are several challenges associated with long term tracking of nanoparticles:
Signal Degradation: Over time, the signals used to track nanoparticles may degrade, leading to inaccurate data.
