    摘要： A method of forming an array of nanostructures includes forming a plurality of seed points on a surface of a substrate, and growing masks from the seed points to create masked regions of the substrate underlying the masks. A remainder of the substrate comprises an unmasked region. Each mask and masked region increase in size with growth time while the unmasked region of the substrate decreases in size. During the growing, the unmasked region is etched to remove material from the substrate in a depth direction, and, simultaneously, unetched structures are formed from the masked regions of the substrate underlying the masks. Each of the unetched structures has a lateral size that increases with depth.

    摘要： Provided are a camptothecin compound containing 7-membered lactone ring, as shown in general formula I, and pharmaceutically acceptable salt thereof, as well as the preparation method and use thereof. In general formula I, R1 is H, a C1˜C3 alkyl, acetyl or propionyl; R2 is H, a C1˜C6 alkyl, a C3˜C6 cycloalkyl, piperidyl; or a C1˜C6 alkyl substituted by an amino; R3 is H, a C1˜C3 alkyl, or a C1˜C6 alkyl substituted by an amino; R4 is H, a hydroxyl, or a C1˜C6 alkoxy; R5 is H, or a C1˜C6 alkoxyl; or R4 and R5 are linked to each other to form —OCH2O— or —OCH2CH2O—. The compound has good anti-tumor activity, and can be clinically used via oral administration, intravenous injection, and intramuscular injection, among others.
