What is nanoparticles?

Nanoparticles are microscopic particles with at least one dimension between 1 and 100 nanometers. They exhibit unique properties compared to their bulk counterparts due to their high surface area to volume ratio and quantum effects. They are used in a wide range of applications, including drug delivery, electronics, cosmetics, environmental remediation, and catalysis.

What other technologies are related to nanoparticles?

nanoparticles Competitor Technologies

M
Microparticles
No summary available
Microparticles (1-1000 μm) offer simpler, often cheaper manufacturing compared to nanoparticles, and may be sufficient for applications where nanoscale effects aren't critical, such as drug delivery for localized treatment.
L
Liposomes
No summary available
Liposomes, spherical vesicles with a lipid bilayer, are a well-established drug delivery system. They can encapsulate both hydrophilic and hydrophobic drugs and are biocompatible, offering an alternative to nanoparticles for targeted drug delivery.
M
Micelles
No summary available
Micelles, self-assembled aggregates of amphiphilic molecules, are another drug delivery alternative. While generally smaller than liposomes, they can solubilize poorly water-soluble drugs and offer relatively simple preparation.
Q
Quantum Dots
No summary available
While sometimes considered a type of nanoparticle, quantum dots compete in applications like bioimaging. Their unique optical properties (size-tunable emission) provide high sensitivity, which competes with other nanoparticle imaging agents.
V
Viral Vectors
Viral vectors are genetically engineered viruses used to deliver genetic material into cells. In gene therapy applications, they compete with non-viral nanoparticle-based delivery systems.
E
Exosomes
No summary available
Exosomes are naturally occurring nano-sized vesicles secreted by cells. They are being explored as drug delivery vehicles and for diagnostic purposes, offering a biocompatible alternative to synthetic nanoparticles.
