<h2>What are nanoparticles and advanced nanomaterials?</h2>
&nbsp;
Nanoparticles and advanced nanomaterials are materials with at least one dimension in the 1&ndash;100 nanometer range that exhibit physical, chemical, or optical properties substantially different from their bulk counterparts due to quantum effects, high surface-to-volume ratios, and size-dependent electronic behavior. Research-relevant categories include gold nanoparticles with size-tunable surface plasmon resonance used for sensing and imaging; silver nanoparticles with antimicrobial properties; iron oxide nanoparticles for MRI contrast enhancement and magnetic separation; lipid nanoparticles for RNA and small molecule delivery; and quantum dots for fluorescent bioimaging.

<h2>How to choose nanoparticles and nanomaterials</h2>
&nbsp;
Choose gold nanoparticles for plasmonic sensing, SERS, and bioimaging applications
Gold nanoparticles have size- and shape-tunable surface plasmon resonance that can be used in colorimetric sensing assays, surface-enhanced Raman spectroscopy (SERS), and as contrast agents in photoacoustic imaging, with surface conjugation chemistries available for attaching antibodies, nucleic acids, or other targeting ligands.
Choose silver nanoparticles for enhanced SERS or antimicrobial research
Silver nanoparticles have stronger plasmonic enhancement than gold at similar size, making them particularly effective for SERS-based detection applications, and their antimicrobial activity against a broad range of bacteria makes them tools for studying antimicrobial mechanisms and for developing antibacterial coatings.
Choose iron oxide nanoparticles for magnetic separation and MRI research
Superparamagnetic iron oxide nanoparticles respond to external magnetic fields without retaining permanent magnetization, enabling magnetic cell separation, targeted delivery, and use as MRI contrast agents, with the superparamagnetic property dependent on particle size being below approximately 20 nm.
Choose lipid nanoparticles for intracellular nucleic acid delivery
Lipid nanoparticles, particularly ionizable lipid nanoparticles, are the leading delivery platform for mRNA and siRNA, protecting nucleic acid cargo from degradation, facilitating endosomal escape after cellular uptake, and releasing cargo intracellularly. Their composition, including ionizable lipid, helper lipid, cholesterol, and PEG-lipid ratios, determines delivery efficiency and biodistribution.
Choose quantum dots for stable, bright, size-tunable fluorescence
Quantum dots are semiconductor nanocrystals whose fluorescence emission wavelength is determined by particle size, providing size-tunable emission across the visible and near-infrared spectrum with narrow emission peaks, high quantum yield, and exceptional photostability compared with organic fluorescent dyes.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
Lipid nanoparticles for RNA delivery are typically composed of four components: an ionizable lipid that facilitates endosomal escape, a phospholipid helper like DSPC that provides structural stability, cholesterol that enhances membrane fusion, and a PEG-lipid that controls particle size and reduces non-specific protein adsorption. As of 2026, lipid nanoparticle formulation research has expanded substantially following the success of mRNA vaccine platforms, with ionizable lipid composition, lipid-to-RNA ratio, and PEG-lipid density recognized as critical variables for delivery efficiency and tissue biodistribution.
