    Abstract: Provided are a method for dual-color imaging of sodium/calcium activities using a two-photon fluorescent probe and a method for preparing the two-photon fluorescent probe. The disclosed two-photon fluorescent probe for detecting calcium ions near the cell membrane reacts with calcium cations to exhibit strong two-photon fluorescence and may be selectively and easily loaded into the cell membrane by forming a complex with a calcium ion. Further, it allows imaging of the distribution of calcium cations in a living cell or tissue since it can selectively detect calcium ions in the living cell or tissue at a depth of 100 to 200 ?m for more than 60 minutes. In addition, by staining the living cell or tissue with two probes of different fluorescent colors, the calcium and sodium activities can be imaged simultaneously at different channels.

  • Patent number: 8084647
    Abstract: A two-photon probe for real-time monitoring of intracellular calcium ions is provided. The two-photon probe is very suitable for real-time imaging of intracellular calcium ions, shows 20˜50-fold TPEF enhancement in response to Ca2+, has a dissociation constant (KdTP) of 0.14±0.02 to 0.25±0.03 ?M, and emits 5-fold stronger TPEF than currently available one-photon fluorescent Ca2+ probes. Unlike the previously available probes, the two-photon probe can selectively detect dynamic levels of intracellular free Ca2+ in live cells and living tissues without interference from other metal ions and from the membrane-bound probes. Moreover, the two-photon probe is capable of monitoring the calcium waves at a depth of 100-300 ?m in live tissues for 1,100-4,000 s using two-photon microscopy (TPM) with no artifacts of photo-bleaching. Further provided are a method for preparing the two-photon probe and a method for real-time monitoring of intracellular calcium ions using the two-photon probe.

  • Patent number: 7897504
    Abstract: A method for fabricating a semiconductor device, in which a lifting phenomenon can be prevented from occurring in forming an amorphous carbon film on an etched layer having tensile stress. According to the invention, since a compression stress on the etched layer or the amorphous carbon film can be reduced or a compression stress film is formed between the etched layer or the amorphous carbon film to prevent a lifting phenomenon from occurring and thus another pattern can be formed to fabricate a highly integrated semiconductor device.

  • Publication number: 20080268608
    Abstract: In a method of fabricating a flash memory device, after an isolation trench is formed, a bottom surface and sidewalls of the trench are gap-filled with a HARP film having a favorable step coverage. A wet etch process is performed such that the HARP film remains on the sidewalls of a tunnel dielectric layer, thereby forming a wing spacer. Accordingly, the tunnel dielectric layer can be protected and an interference phenomenon can be reduced because a control gate to be formed subsequently is located between floating gates.
