Applications:

Zinc sulfur manganese silica Core-Shell Nanoparticles

Due to their unique combination of luminescent, biocompatible, and customizable properties, ZnS

/SiO₂ core-shell nanoparticles have a wide range of applications in various fields:

Biomedical Applications

Fluorescence Imaging and Diagnostics:

The bright, stable fluorescence of ZnS/SiO₂ nanoparticles makes them excellent candidates for biological imaging. They can be used in cell imaging, in vivo imaging, and multimodal imaging (e.g., combined with magnetic resonance imaging (MRI) or positron emission tomography (PET) for cancer diagnostics).

The functionalizable silica shell enables the attachment of specific targeting moieties such as antibodies, aptamers, or peptides to facilitate targeted imaging of specific cells or tissues, such as tumor cells, or to monitor gene expression in vivo.

Drug Delivery Systems:

The silica shell can be used as a drug delivery vehicle by encapsulating therapeutic agents in the core or by using surface-modified functional groups to attach drugs to the nanoparticle surface. The luminescence of the particles allows for real-time tracking of the drug’s distribution, release, and therapeutic effect in living organisms.

The high surface area and biocompatibility of the silica shell also make these nanoparticles suitable for delivering chemotherapeutic agents or gene therapy vectors to targeted areas in the body, enhancing the precision of the treatment and reducing side effects.

Biosensing and Diagnostics:

ZnS

/SiO₂ nanoparticles can be used in biosensing applications due to their strong fluorescence and ability to functionalize with specific recognition elements. For instance, they can be used in disease biomarker detection, where the nanoparticles are designed to bind to specific analytes such as DNA, proteins, or small molecules, producing a measurable fluorescent signal.

They can also be utilized in environmental biosensors for detecting pathogens or toxins in water or air samples.
