Published: July 2004

In this presentation we describe a novel methodology for ultra-sensitive fluorescence immunoassays based on a new class of fluorescent biomarkers, which are strongly enhanced by nano-size metallic particles. Specifically, we discuss development of the immunoassay on the surfaces coated with metallic particles for high sensitivity detection of cardiac markers. This technology will allow detection of the biomarkers in serum and blood without separation and amplification steps. We present an experimental platform that uses front-face excitation in total internal reflection mode for efficient rejection of background fluorescence.

The detection of disease-related protein biomarkers plays a crucial role in the early diagnosis, treatment, and monitoring of diseases. The concentrations of protein biomarkers can vary significantly in different diseases or stages of the same disease. However, most of the existing analytical methods cannot simultaneously meet the requirements of high sensitivity and a wide dynamic range.

Cancer is one of the leading causes of death worldwide, posing a significant threat to human health. Although immunotherapy has shown promise in cancer treatment, its efficacy is often compromised by tumor immune evasion, which hinders treatment outcomes. Therefore, combining immunotherapy with other therapeutic approaches to enhance its effectiveness has become an increasingly accepted strategy in clinical practice.

Progressive forms of interstitial lung diseases, including idiopathic pulmonary fibrosis (IPF), are deadly disorders lacking non-invasive biomarkers for assessment of early disease activity, which presents a major obstacle in disease management. Excessive extracellular matrix (ECM) deposition is a hallmark of these disorders, with fibronectin being an abundant ECM glycoprotein that is highly upregulated in early fibrosis and serves as a scaffold for the deposition of other matrix proteins. Due to its role in active fibrosis, we are targeting fibronectin as a biomarker of early lung fibrosis disease activity via the PEGylated fibronectin-binding polypeptide (PEG-FUD).

Real-time visualization of endogenous enzymes not only helps reveal the underlying biological principles but also provides pathological information for cancer/disease diagnosis and even treatment guidance. To this end, enzyme-activatable fluorescence probes are frequently fabricated that turn their fluorescence signals "on" exclusively at the enzyme-rich region, thus enabling noninvasive and real-time imaging of enzymes of interest at the molecular level with superior sensitivity and selectivity. However, in a complex biological context, commonly used single enzyme-activatable (i.

The () gene family is of rising importance as their fusions are oncogenic, and specific target drugs are available to inhibit the chimera proteins. Pan-TRK antibody, which shows the overexpression of the genes, is a useful tool to detect tumors with or without gene alterations, due to high negative predictive value. Though it is well known that pan-TRK immunopositivity is usually not connected to fusion, the role of other possible genetic alterations is under-researched.
