Abstract: A lens fixing mechanism includes a lens base having a hollow structure and a breach structure formed on the hollow structure and a lens clamp. A ring portion of the lens clamp has an opening and a protruding structure. Two sheets extend outwardly from the opening. The protruding structure protrudes from a periphery toward a center of the ring portion. When the ring portion sleeves the hollow structure to insert the protruding structure into the breach structure and a lens module is inserted into the hollow structure, the sheets are connected to each other to pack the ring portion to contract inwardly, so as to make the protruding structure pass through the breach structure for clamping the lens module and make a portion of the periphery of the ring portion except the protruding structure to clamp a portion of a periphery of the hollow structure except the breach structure.

Abstract: A surveillance device includes a shell, a sensing assembly and a transparent cover. The transparent cover is detachably disposed on the shell, to form an accommodating space together. The sensing assembly is disposed in the accommodating space. The transparent cover comprises a first light-transmitting cover, an annular light baffle and a second light-transmitting cover. The first light-transmitting cover is disposed on the shell and having a through hole. The annular light baffle disposed at the through hole has a first limiting surface and a second limiting surface. The first light-transmitting cover is pressed against the first limiting surface. The second limiting surface faces oppositely away from the accommodating space. The second light-transmitting cover is disposed on the annular light baffle and pressed against the second limiting surface. The first limiting surface and the second limiting surface prevent the second light-transmitting cover from moving toward the accommodating space.

Abstract: Disclosed is a method for the manufacture of microtissues, comprising the steps of: providing a biomaterial substrate; simultaneously seeding a plurality of dermal papilla (DP) cells and keratinocytes on the substrate surface with a predetermined ratio and cellular density; co-culturing for a predetermined period; and carrying the keratinocytes to the substrate surface by the dermal papilla cells, aggregating and finally form a plurality of keratinocyte-dermal papilla cell microtissues, wherein the dermal papilla cells are located in a center of the microtissue and the keratinocytes are sorted to a surface of the microtissue, and the keratinocytes are adult keratinocytes. The method can help to simply and economize the procedures for production of folliculoid microtissues with high-throughput. Once microtissues are transplanted to skin of subject, hair follicles can be regenerated.

Abstract: A method for making a 3D photonic crystal includes: (a) preparing a liquid mixture including a solvent component, a particulate material suspended in the solvent component, and a filler suspended or dissolved in the solvent component, with the proviso that, when the filler is suspended in the solvent component, the filler has an average size smaller than an average size of the particulate material; (b) allowing a 3D photonic structure to grow from the liquid mixture; and (c) removing liquid from the 3D photonic structure. The method can further include (d) removing the particulate material from the 3D photonic structure after the step (c). In this case, the particulate material and the filler are made of different materials.
