Glyconanoparticles exhibit multifaceted effects and hold significant promise in drug delivery and bioimaging. They integrate the benefits of a nano drug delivery system with the multivalent interactions of sugars, thereby significantly enhancing drug targeting capabilities. Assessing their cytotoxic effects is crucial for researchers to evaluate their safety and effectiveness in biomedical applications. CD BioGlyco has a well-established GlycoNano™ Platform and offers a comprehensive glyconanoparticle cytotoxicity assay service.
We have established a comprehensive Preclinical Study system for glyconanoparticles to help advance its use in biomedical applications. The entire program is executed through the following workflow to comprehensively assess the in vitro cytotoxicity of glyconanoparticle:
We are well-versed in various glyconanoparticle preparation methods and develop fucose, lactose, and galactose residue-modified glyconanoparticles, among others. Then we separate glyconanoparticles from unreacted substances and excess reagents by size exclusion chromatography, dialysis, etc., for purification. The products are characterized in detail by nuclear magnetic resonance (NMR), dynamic light scattering (DLS), scanning electron microscopy (SEM), and other technologies.
We assessed the cytotoxic effects of glyconanoparticles on different cell lines, including cell viability, proliferation, and morphology after exposure to glyconanoparticles. Appropriate controls, concentrations, and exposure times are selected based on various study objectives. Specific processes include the following:
MTT assay | The method measures cell viability based on metabolic activity. |
Flow cytometry | It provides a rapid and reliable method to quantify viable cells in cell suspension. |
lactatedehydrogenase (LDH) assay | This method is used to detect cell membrane integrity and cytotoxicity. |
XTT assay | The method is used to assay mitochondrial dehydrogenase activity in living cells. |
Annexin V/PI staining | This method is one of the most sensitive, efficient, and proven methods for the detection of apoptotic cells. |
Morphological observations | It uses microscopy to detect apoptosis by morphology. |
The percentage of cell viability, etc., is calculated based on experimental data. We compile and analyze the data collected from these analyses using appropriate software packages.
We offer a one-stop glyconanoparticle cytotoxicity assay service. This process includes customized experimental design to meet your specific research needs and comprehensive interpretation of results. We will also discuss the results with you to gain insights and understand the implications of your study.

Results: In this study, a multicomponent delivery system based on carbohydrate-functionalized gold nanoparticles conjugated to fluorophores or prodrugs was developed and cellular experiments were utilized to assess the potential applicability of the system as a bioimaging and drug delivery model. The results showed that the system could be used for drug-specific delivery and was more selective for HepG2 cells than HeLa and NIH3T3 cells. Validation with camptothecin (CPT) as a model drug revealed that Au-Gal-BA (CPT) exhibited similar cytotoxicity, excellent specificity, and superior biocompatibility for HepG2 cells. This study provides a reliable strategy for cell-type-specific trafficking.
