It increases the sensitivity of the resistive pulse sensing and enables to detect very short and small molecules. However, this has not yet been shown for glass having a tubular shape, for instance nanocapillaries. In contrast to their solid-state nanopore counterparts, nanocapillaries are cheap, easily fabricated and in the production do not necessitate clean room facilities. Nanocapillaries made out of glass-like materials such as quartz or borosilicate glass can be shrunken under a scanning electron microscope beam. Since the shrinking is caused by the thermal heating of the electrons, increasing the beam current increases the shrink rate. Higher acceleration voltage on the contrary increases the electron penetration depth and reduces the electron density causing slower shrink rates. This allows to fine control the shrink rate and to stop the shrinking process at any desired diameter. A shrunken nanocapillary may detect DNA translocation with six times higher signal amplitudes than an unmodified nanocapillary. The invention opens a new path to detect small and short molecules such as proteins or RNA with nanocapillaries and also increase the sensitivity of other techniques such as SNOM or SCIM, which also rely on conical glass capillaries.

Bent glass plate for optical use and fabrication method thereof

Номер: US20160039705A1
Принадлежит: Japan 3D Devices Co Ltd

With conventional bent glass plates and fabricating method thereof, it has been difficult to fabricate bent glass plates with high productivity while achieving both high shape precision and high surface smoothness. According to the present invention directed to a glass plate with 2 mm or less thickness, a bent glass plate for optical use with a shape precision PV value of 50 um or less and a surface roughness Ra value of 5 nm or less was achieved by appropriately controlling the temperature of the glass plate, the temperatures of upper and lower press dies, and the press pressure; and quickly and uniformly cooling the glass plate to a predetermined temperature.

Method for supporting a glass sheet

Номер: US20160039706A1
Принадлежит: Glasstech Inc

A method for supporting a heated glass sheet in connection with a glass processing operation may include adjusting a support structure so that multiple spaced apart support members of the support structure cooperate to define a shape that corresponds to a desired end shape of the glass sheet. The method may further include contacting the glass sheet with the support members until the glass sheet has been sufficiently cooled. Furthermore, the support structure may include a frame and a support assembly associated with the frame, the support assembly including the support members and a support connected to the support members such that at least a portion of each support member is adjustable with respect to the support. The support may further be connected to the frame at two locations on the frame such that the support spans an open area between the two locations on the frame.
