Illuminating the World of Plasmonic Nanoparticles: Unveiling the Mystery of Plasmons

Submitted by RichardG on Wed, 01/31/2024 - 23:43

Surface plasmon resonance (SPR) and surface-enhanced Raman scattering (SERS) are two key surface plasmon technologies that ultimately enable single-molecule-level chemical and biological sensors. Due to the tremendous progress in solution-based synthesis methods, plasmonic nanoparticles with various complex shapes (e.g., spheres, rods, and prisms) have been widely used for surface plasmon resonance and surface-enhanced Raman scattering sensing. Localized surface plasmon resonance (LSPR) around plasmonic nanoparticles enables very high SERS enhancement and SPR sensitivity.

Gold Nanoparticles in Medicine: A Tiny Marvel with Big Potential

Submitted by RichardG on Wed, 01/03/2024 - 18:43

With the continuous development of nanotechnology, gold nanoparticles are widely used in the field of medicine. Gold nanoparticles not only have good controllability, biocompatibility, and biosorption, but also have a high degree of stability, and can achieve specific biometrics and functions through surface modification. Therefore, it has become an important nanomaterial in biomedicine.

The Role of Gold Nanoparticles

Carrageenans as a Versatile Tool in Drug Delivery

Submitted by RichardG on Wed, 05/24/2023 - 23:38

Drug delivery is the process of administering pharmaceutical substances to targeted areas in the body. It plays a vital role in the effective treatment of various diseases. However, drug delivery is often challenged by the body’s natural defenses, such as the gastrointestinal tract and the immune system, which can prevent the drug from reaching its intended target. Carrageenans, a family of sulfated polysaccharides derived from red seaweed, have been shown to be an effective tool in drug delivery due to their unique properties.

What Are Phosphate Magnetic Particles?

Submitted by RichardG on Wed, 05/24/2023 - 23:36

Phosphonates or phosphonic acids are organic compounds containing C–PO(OH)2 or C–PO(OR)2 groups (where R = alkyl, aryl). Most phosphonates are highly water-soluble, while phosphonic acids are only sparingly soluble. Phosphonates are not volatile and are poorly soluble in organic solvents. Normally they are more efficient FRs than phosphates, but raw materials for phosphonates are more expensive than for phosphates.
