Web21 apr. 2015 · Many potent therapeutic compounds, such as paclitaxel (PTX), encountered delivery issue due to poor water solubility. To improve solubility of these hydrophobic molecules, various formulations of nanoparticles have been developed in the past decades, many of which were liposome and micelle-based. 1, 2 However, the large size of … Web11 apr. 2024 · Polar molecules are generally hydrophilic in nature and not hydrophobic. Water is a polar solvent as each H 2 O molecule is polar in nature. It comprises two polar O-H bonds having an electronegativity difference of 1.24 units between the covalently bonded oxygen (E.N = 3.44) and hydrogen (E.N = 2.20) atoms. Oxygen, being more …
