QuTEM liposomes


Liposomes serve as exceptional drug delivery systems owing to their low toxicity, target specificity, and adaptability. With new liposomal drugs entering the market each year, the demand for a deeper understanding of liposomal drug carriers is increasingly crucial. To successfully integrate into the pharmaceutical market, rigorous characterization adhering to regulatory standards must be conducted.  

QuTEM’s robust analysis methods enable direct visualization of the drug product and provide comprehensive data on liposomal drug properties, including size distribution, encapsulation efficiency, and lamellarity that correlate to stability, efficacy, and release kinetics.
