摘要:
In various aspects and embodiments, the present invention is directed to versatile, label-free method for the quantitative and qualitative detection of biomarkers and/or other compounds in a fluid sample using functionalized microparticle aggregates. In these methods, micron-scale particles are functionalized to specifically interact with the biomarker being measured and added to the sample to form aggregates, the size and number of which are counted to find a volume fraction and/or number fraction of aggregates in the sample. There is a direct correlation between the volume fraction and number fraction of these aggregates and the concentration of the corresponding biomarker. By comparing the measured volume fraction and/or number fraction of aggregates in the sample to a calibration curve, the concentration of that biomarker may be determined even for biomarkers or other target compounds in samples at very low concentrations, without the need for fluorescence and enzyme labelling of antibodies.

A radiating element includes a supporting element and a plurality of radiating units formed at one end of the supporting element. Each of the radiating units has a lower surface facing towards the supporting element and an upper surface facing away from the supporting element. The radiating element further includes a first and second dividing pieces symmetrically disposed on each of the radiating units. The radiating element also includes a loading element formed on the lower surface of each of the plurality of radiating units, wherein the loading element extends outward from the supporting element and along an edge of the radiating unit. Moreover, the radiating element includes an electrical connecting element for connecting the radiating units to a feeding cable, the electrical connecting element being lower than the upper surfaces of the radiating units.

摘要:
A lamp device includes a lamp seat defining a first through hole, a lamp main body defining a second through hole, and a holding mechanism. The holding mechanism includes a bolt, a first nut, and a second nut. The bolt includes a head and a spindle connecting to the head. The spindle defines first screw threads at the opposite end from the head and second screw threads adjacent to the first screw threads. The threads per inch of the first screw threads are smaller than that of the second screw threads. The spindle passes though the first through hole and the second through hole to connect with the lamp main body and the lamp seat. The first nut and the second nut are respectively fit over the first screw threads and the second screw threads.
摘要:
A telephone includes a handset, a base and a hook. The handset includes a earpiece defining a slot. The base defines a first recess and an opening. The first recess is configured for receiving the earpiece. The opening includes a second recess and a through hole defined in a bottom of the second recess. The hook includes a head and an elastic rod protruding from the head. The rod is rotatably received in the through hole. The head is received in the second recess and able to rotate and insert into the slot for supporting the handset.
摘要:
An exemplary lid lock mechanism (20) includes a main body (22) and a lid (24). Two resilient hooks (222) and two resisting portions (224) are formed on an inner surface of the main body. The lid includes a lid cap (242). Two hooking portions (246) and two extending pieces (248) are formed on a surface (244) of the lid cap. The hooking portions are engaged with the resilient hooks of the main body when the lid is connected to the main body. To detach the lid from the main body, the hooks of the hooking portions are disengaged from the resilient hooks of the main body.
