What do you understand by "the aggregation of DNA-functionalized nanoparticles"? Is it about how to make hybrid particles like DNA-nanogold, or is it about the particles' tendency to self assembly?

Sounds like typical nanotech to me.

By which I define 'nanotech' as "a branch of science dedicated to turning ordinary physical chemistry into fantastic-sounding buzzwords, producing large research grants in the process".

It think its neither.
Self-aggregation in this context probably just means that particles tend to clump together (randomly, self-assembly sort of implies some sort of structure) which would presumably would be a major problem when trying to analyze them.

Btw, although I agree that the nanotech area is ripe with buzzwords this is actually one example where the word actually means something. "Functionalized nanoparticles" are simply nanoparticles with some sort of property (they can e.g be magnetic) that makes them easy to find/analyze that have been functionalized; in this example coated with a substance that binds to DNA. The neat thing about this is that you can disperse them in whatever you are are trying to analyze (they can even be injected) and they will then to the DNA (or whatever); the sample can then by analyzed using a magnetic sensor.

It it a very promising technology and I even think it is already in practical use.

Just for the sake of clarity, where did you come across this phrase? If you could, give us a link to the article, or post a quote of the entire paragraph in which the phrase was used (getting proper credit to the author, of course). Putting it in context might help.
 

1. What are DNA-functionalized nanoparticles?

DNA-functionalized nanoparticles are tiny particles that have been coated with strands of DNA. These nanoparticles have unique properties that make them useful in a variety of scientific and medical applications.

2. How are DNA-functionalized nanoparticles made?

DNA-functionalized nanoparticles are typically made by coating a core material, such as gold or silica, with a layer of DNA molecules. This can be achieved through various methods, including chemical synthesis, self-assembly, or surface modification techniques.

3. What are the advantages of using DNA-functionalized nanoparticles?

DNA-functionalized nanoparticles have several advantages over traditional nanoparticles. They have a high surface area to volume ratio, making them efficient carriers for drug delivery. They also have a high degree of biocompatibility and can be tailored to target specific cells or tissues.

4. What are the potential applications of DNA-functionalized nanoparticles?

DNA-functionalized nanoparticles have a wide range of potential applications in fields such as medicine, biotechnology, and environmental science. They can be used for targeted drug delivery, disease diagnosis and imaging, gene therapy, and environmental remediation.

5. Are there any ethical concerns surrounding the use of DNA-functionalized nanoparticles?

As with any new technology, there may be ethical concerns surrounding the use of DNA-functionalized nanoparticles. These may include issues related to privacy, potential unintended consequences, and the responsible use of this technology in research and medical treatments.
