A membrane-anchored aptamer sensor for probing IFNγ secretion by single cells.

A membrane-anchored aptamer sensor for probing IFNc secretion by single cells†

Cell-surface sensors for real-time probing of cellular environments.

The ability to explore cell signalling and cell-to-cell communication is essential for understanding cell biology and developing effective therapeutics. However, it is not yet possible to monitor the interaction of cells with their environments in real time. Here, we show that a fluorescent sensor attached to a cell membrane can detect signalling molecules in the cellular environment. The senso...

Development of an aptasensor for electrochemical detection of exosomes.

Exosomes are small (50-100 nm in diameter) vesicles secreted from various mammalian cells. Exosomes have been correlated with tumor antigens and anti-tumor immune responses and may represent cancer biomarkers. Herein, we report on the development of an aptamer-based electrochemical biosensor for quantitative detection of exosomes. Aptamers specific to exosome transmembrane protein CD63 were imm...

Radiosensitization of breast cancer cells using AS1411 aptamer-conjugated gold nanoparticles

Introduction: A main choice for cancer treatment is radiotherapy. But, the radiotherapy disadvantage is damages caused by radiation given to normal tissues/organs surrounding cancer. One way to avoid this is via increasing radiosensitization of cancer cells. Gold nanoparticles (GNPs) have shown sensitizing effect on cancer cells by enhancing their absorbed dose. Unlike earlier ...
