Our cutting-edge analytical solutions, combining CryoTEM with our in-house image analysis software, enables to accurately assesses liposomes and drug delivery characteristics through a complete portfolio of solutions such as overall morphology, lamellarity, membrane thickness, packaging, and circularity. 

Packaging assessment

Our cryo-TEM analyses offer a detailed view of the packaging of your liposomes, providing valuable insights into their encapsulation efficiency. This data is crucial for evaluating the performance of drug delivery systems and is delivered conveniently to you in a comprehensive analytical report.

CryoTEM preparation and imaging allows to observe the specimen and its particles in a near-native hydrated state. Through this method, the inner content of the particles can be directly visualized and assessed, allowing a straight forward discrimination between particles rich in drug and empty ones.

Our semi-automated detection method using our in-house software solution presents a representative histogram (left) that effectively displays the liposome packaging. The corresponding image (right) simplifies data interpretation by overlaying detected and classified particles with clear blue/green/red outlines. This allows for a visual, user-friendly understanding of encapsulation efficiency. The percentage of encapsulation can be correlated to the efficiency of the drug release. This data is provided in the analytical report.

Lamellarity Assessment

Insights on the liposomes lamellarity is essential for predicting drug release kinetics. CryoTEM combined with image analysis from our software package allows to distinguish liposomes based on their lamellarity.

Maximize Efficiency and Efficacy with Precise Measurement of Lipid Bilayer Thickness

Recognizing the significant impact of lipid bilayer thickness on the efficiency and efficacy of liposomal products, we’ve made it an essential parameter to monitor in the design of liposome-based drug carriers. By harnessing the capabilities of both cryoTEM and our proprietary VAS software, you can measure the thickness of the lipid bilayer with unmatched precision.
