The present study aimed to develop polyethylene glycol–liquid crystals (PEG-LC) ointment formulations, assess their formulation characteristics, and establish biocompatibility impact on transdermal drug administration. PEG-LC formulations were prepared using a hydrophilic molecule, p-aminobenzoic acid (PAB). Formulation characterizations such as small-angle X-ray scattering, viscosity, pH, zeta...

Only in liquid environment can most biomolecules maintain their biological activity, the realization of terahertz (THz) spectrum detection water-bearing has an important application value for research function and structure active non-invasive biomedical detection. In this paper, by using THz radiation source generated LiNbO3 light rectification, combing with local electric field enhancement ef...
