Acute myocardial infarction (AMI) is the single leading cause of worldwide mortality and morbidity. Heart-type fatty acid-binding protein (H-FABP) cardiac troponin I (cTnI), as biomarkers emerging at different stages AMI, have complementary advantages in terms specificity sensitivity. Therefore, we developed a magnetic immunoassay method based on surface-enhanced Raman scattering (SERS) to detect H-FABP cTnI simultaneously.

Two-photon fluorescence (TPF) z-scan techniques carried out, a significant enhancement in the TPA cross section was observed for ST-G2, which possesses largest generation number among studied samples. By using different solvents, nonlinear optical (NLO) response most polar solvent. Ultrafast pump-probe experiments performed to...

Abstract Sepsis is a systemic inflammatory response syndrome caused by infection. The mortality rate as high 30%−50%. Early diagnosis and treatment can significantly improve the of patients with sepsis. Therefore, we have developed SERS-based magnetic immunoassay method that uses principle sandwich to quantitatively detect Interleukin 6 (IL-6) Procalcitonin (PCT). In this article, two different Raman reporter molecules are embedded in middle Au@Ag shell coupled tracer antibody form SERS...

A new organic dye, trans-4, 4′-bis(pyrrolidingl) stilbene (BPAS), with large two-photon absorption (TPA) and three-photon (3PA) has been synthesized. The molecular TPA cross section σ2′ at 550–670 nm the 3PA σ3′ 720–1000 have measured. biggest was 5.77 × 10-47 cm4s/photon 27 10-75 cm6 s2 600 980 nm, respectively. In experiment process we found that strongest wavelength is not two times of linear wavelength, but there some blue shift. 3PA-induced optical power-limiting properties also illustrated nm.

Sepsis is a systemic inflammatory response syndrome caused by infection, and common disease in intensive care units (ICUs), whereby the mortality rate as high 30% to 50%. Early diagnosis treatment can significantly reduce of patients with sepsis. We have developed method based on SERS for rapid quantitative detection IL-6.

As common psychotropic drugs, ketamine (KET) and amphetamine (AMP) are often consumed by drug users at the same time, which seriously threatens people's health. Therefore, study of simultaneous detection methods for KET AMP is imperative. In this study, a novel method in serum was established on basis surface-enhanced Raman scattering (SERS). The antibodies were attached Au@Ag core-shell nanoparticles embedded with different reporters as substrates. labelled antigens KET-BSA AMP-BSA linked...

Spatial relationships exhibited among regions in an image play important role the interpretation of a scene. While humans have innate ability to recognize spatial relations, it has been difficult produce algorithms model these relationships. There several attempts at defining between digital image, most recently, with use fuzzy set theory. In previous paper, we compared three algorithmic methods for relations gain insight into this complex situation. Here, examine neural network structures...

Laser-tissue vaporization through a fiber catheter is evolving into major category of surgical operations to remove diseased tissue. Currently, during surgery, the surgeon still relies on personal experience optimize techniques. Monitoring tissue temperature laser-tissue would provide important feedback surgeon; however, simple and low-cost sensing technology, which can be seamlessly integrated with catheter, not available. We propose monitor by detecting blackbody radiation (BBR) between...
