What was the primary methodological change in the HMLC technique used in the study?

Use of a micellar mobile phase with reduced solvent usage.

HMLC is a modified version of the high-performance liquid chromatographic (HPLC) technique, where the composition of the mobile phase is a modified aqueous micellar mobile phase with a major part of water, surfactant (above critical micellar concentration) and low concentration of short-chain alcohols (i.e., 1-propanol, 1-butanol, 1-pentanol) as an organic modifier.

Considering the environmental impacts discussed, why is the HMLC method considered 'green'?

It involves less waste and uses low-toxicity solvents.

Nevertheless, a hybrid micellar liquid chromatography (HMLC) can also be used. HMLC is a modified version of the high-performance liquid chromatographic (HPLC) technique, where the composition of the mobile phase is a modified aqueous micellar mobile phase with a major part of water, surfactant (above critical micellar concentration) and low concentration of short-chain alcohols (i.e., 1-propanol, 1-butanol, 1-pentanol) as an organic modifier.

What is hyperthermia commonly used to treat?

Cancer

Hyperthermia, the mild elevation of temperature to 40–45 °C, can induce cancer cell death and enhance the effects of radiotherapy and chemotherapy.
