Dual-Purpose 3D-Silica Nanostructure Matrix for Rapid Epigenetic Reprogramming of Tumor Cell to Cancer Stem Cell Spheroid.

Cancer stem cells (CSCs), a rare subpopulation responsible for tumorigenesis and therapeutic resistance, are difficult to characterize and isolate. Conventional method of growing CSCs takes up to 2-8 weeks inhibiting the rate of research. Therefore, rapid reprogramming (RR) of tumor cells into CSCs is crucial to accelerate the stem cell oncology research.

Self-functional gold nanoprobes for intra-nuclear epigenomic monitoring of cancer stem-like cells.

Cancer epigenomic-environment is a core center of a tumor's genetic and epigenetic configuration. Surveying epigenomic-environment of cancer stem-like cells (CSC) is vital for developing novel diagnostic methods and improving current therapies since CSCs are among the most challenging clinical hurdles. To date, there exists no technique which can successfully monitor the epigenomics of CSC.

Evaluation of effect of two different functionalized nanoparticle photodynamic therapy on nanohardness of root dentin-An in vitro study.

Introduction: The aim of this study was to evaluate the effect of functionalized nanoparticle photodynamic therapy on Nano hardness of root dentin METHODOLOGY: Fifty single rooted lower premolars were decoronated and sectioned into two halves. Then the samples were embedded horizontally in to the acrylic resin to expose the dentin surface. Baseline nanohardness was done at midroot level using a Nanohardness tester.
