Abstract: The present invention provides a blank liposome with ginsenoside Rg3 or its analog as the membrane material, preparations and uses thereof. The disclosed blank liposome has a membrane comprising a lipid and a ginsenoside analog of Formula I, presenting remarkable advantages in film formation, encapsulation efficiency, targeted drug delivery, blood circulation time, stability, safety and homogeneity. It can also be used to load active substances of drugs and cosmetics, biological agents, polynucleotides or oligonucleotides, and the preparation process is convenient.

Abstract: Among others, the present invention provides a blank liposome, preparation methods thereof, and a loaded liposome including the blank liposome and an active substance. The liposomes have a membrane comprising lipids and a ginsenoside of Formula I, and may further comprise a surfactant, a heat-sensitive excipient, a pH sensitive material, or an ion additive.

Abstract: A method and system for providing a magnetic recording transducer are disclosed. The method and system include providing a metallic underlayer directly on a portion of an insulating layer. The method and system also include forming a perpendicular magnetic recording pole on the metallic underlayer. The perpendicular magnetic recording pole has a top, a bottom narrower than the top, and sides. The perpendicular magnetic recording pole has a pole removal rate. The method and system also include providing an insulator having an insulator removal rate. The insulator substantially surrounds at least the sides of the perpendicular magnetic recording pole. The metallic underlayer has a removal rate that is at least one of less than the insulator removal rate and substantially equal to the pole removal rate.
