Abstract: The present invention relates to a monosaccharide-tagged nano-liposome, which is characterized that the targeting monosaccharide is conjugated to cholesterol and the monosaccharide-conjugated cholesterol is incorporate into the phospholipid bilayer. The nano-liposome of present invention exhibits the ability to carry the loaded drug to target cells, such as cancer cells and cancer stem cells in a tumor tissue, and may be internalized by endocytosis to produce direct cytotoxicity or suppress stemness gene expression, so as to avoid toxicity to normal cells and effectively improve the therapeutic effect of cancer clinical medication and radiation therapy.

Abstract: The present invention discloses an antenna diversity switch, used for receiving and transmitting RF signals for dual-mode co-existence wireless communication system. The antenna diversity switch comprises a first transmitting port; a second transmitting port; a receiving port; a first control unit, electrically connected between the first transmitting port and a first antenna; a second control unit, electrically connected between the first transmitting port and a second antenna; a third control unit, electrically connected between the second transmitting port and the first antenna; a forth control unit, electrically connected between the second transmitting port and the second antenna; a fifth control unit, electrically connected between the receiving port and the first antenna; a sixth control unit, electrically connected between the receiving port and the second antenna. The antenna diversity switch according to the present invention meets the requirement of IEEE 802.
