Differential scanning calorimetry (DSC) of these materials was performed using a TA Instruments Q200 DSC system (TA Instruments-Waters L.L.C., New Castle, DE). Sample sizes of 10 to 18 mg were prepared using crimped aluminium pans. All liquid-based samples were freeze dried overnight to dry the material. Samples were tested using heating/cooling rates of 10 °C/min from −50 to 250 °C. The glass transition temperature (Tg) was determined from the midpoint in the second heating cycle.
Q200 dsc system
Manufactured by TA Instruments
The Q200 DSC system is a thermal analysis instrument designed to measure the heat flow associated with physical and chemical changes in materials as a function of temperature and time. It is capable of detecting and quantifying thermal transitions such as melting, crystallization, and glass transitions. The Q200 DSC system provides accurate and reliable data to support materials characterization and development across a wide range of industries.

To assess the optimal solid/liquid lipid ratio for the NLC formulation, the differences in the melting points of different solid/liquid lipid mixtures were assessed using differential scanning calorimetry (DSC) (Savić et al., 2019 (link)). Samples of mixtures with different ratios of monolaurin and Capryol-90 (3:2, 2:1, 7:3, 3:1) were heated from 30 °C to 90 °C at a heating rate of 10 °C/min using a Q200 DSC system (TA Instruments, New Castle). Measurements were conducted under a constant nitrogen flow of 20 mL/min.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
