A biocatalyst is an enzyme that speeds up or slows down the rate at which a chemical reaction occurs and certain processes by 108 times. It used as anticancer agent because it targets drug activation inside tumor microenvironment while limiting damage to healthy cells. Biocatalysts have been for synthesis of different heterocyclic compounds also in nano delivery systems. The use nano-biocatalys...
BACKGROUND The detection and differentiation of intracardiac masses is still challenging and may include neoplasms and thrombi. The aim of this study was the investigation of a targeted, fibrin-specific contrast agent (EP-2104R) for molecular targeted magnetic resonance imaging (MRI) of left atrial clots. METHODS AND RESULTS Chronic human thrombi were surgically implanted in the left atrial a...
a review on application of nanotechnology for early breast cancer detection based on medical imaging
breast cancer is characterized by a distinct metastatic pattern involving the regional lymph nodes, bone marrow, lung and liver. tumour cell migration and metastasis share many similarities with leukocyte trafficking, which is critically regulated by chemokines and their receptors. detection of breast cancer and its metastasis at the earliest stage is important for the management and prediction...
nanotechnology has slowly but steadily revolutionized the diagnosis, imaging and treatment of cancer. detecting cancer at earliest stages, locating the tumor at different areas in the body and specific delivery of the drugs to malignant cells including surgically inaccessible tumors are the core areas of medical and pharmaceutical research across the world. in this endeavour, nanodevices have e...
Targeted contrast-enhanced ultrasound (molecular ultrasound) is an emerging imaging strategy that combines ultrasound technology with novel molecularly-targeted ultrasound contrast agents for assessing biological processes at the molecular level. Molecular ultrasound contrast agents are nano- or micro-sized particles that are targeted to specific molecular markers by adding high-affinity bindin...
This paper describes a new class of immunotargeted and cancer specific CT contrast agents, which enable CT imaging of cancer at cellular and molecular resolution. The method is based on the development of gold nano-probes that specifically and sensitively target in vivo tumor specific antigens, while inducing distinct contrast in CT imaging (increased x-ray attenuation). The overall goal of thi...
