Microfibers are key components in construction of fiber-based materials, biomimetic microsensors, and other microstructures. Due to the scaling law, adhesion forces such as van der Waals force or electrostatic micro world play a more dominant role than gravity, causing difficulties precise pick-and-place objects. In this paper, we propose capillary force-based method for handling microfibers. T...

The reflectance factors of transparent fibers, free delustering agent, are predicted by geometric as well as Kubelka-Munk models.&#10 Transparent fibers are simulated by a net of glass capillary tubes containing different solutions of dyestuffs. Based on the results, prediction of the reflectance factor of capillary net by geometric model is relatively better than those obtained from Kubelka-Mu...

Pulmonary capillary hemangiomatosis (PCH) is a rare and controversial entity that known to be cause of pulmonary hypertension microscopically characterized by proliferation dilated capillary-sized channels along in the alveolar walls. Clinically, it mostly seen adults. PCH’s main clinical presentations are progressive dyspnea, fatigue, hemoptysis, palpitations later irreversible right-sid­ed he...

A simple capillary enzymatic biosensor was developed. This was prepared by simply coating a dissolvable membrane containing enzyme/s on the inner wall of a square glass capillary. An easy measurement was carried out by capillary force sample introduction with concurrent enzyme release and a reaction with a certain substrate. Enzyme-release capillary (ERC) biosensors showed long-term storage sta...

336 CLINICALCHEMISTRY, Vol.25,No. 2, 1979 capillary, the nine negative specimens were sampled and processed. This experiment was repeated with a plastic capillary. With the glass capillary, the first specimen was positive as expected, but the next eight specimens were also positive. The last specimen was negative. For the plastic capillary, the first specimen was positive and the next three ori...

An innovative vacuum capillary pneumatic actuation concept that can be used for point-of-care testing has been investigated. The vacuum glass capillaries are encapsulated within a laminated pouch and incorporated into the fluidic card. Vacuum glass capillaries broken by external force such as finger pressure, generate the pneumatic forces to induce liquid flow in the fluidic system. The sizes o...

Assembly of nanowires into ordered macroscopic structures with new functionalities has been a recent focus. In this Letter, we report a new route for ordering hydrophilic Ag nanowires with high aspect ratio by flowing through a glass capillary. The present glass capillary with well-defined silver nanowire films inside can serve as a portable and reusable substrate for surface-enhanced Raman spe...
