  • NanoSight Ltd.

Jan 2011
Members of the department of biomedical engineering at Johns Hopkins University School of Medicine in Baltimore are using the LM10-HS, a nanoparticle tracking analysis system made by NanoSight Ltd. of Salisbury, UK, to study self-assembled polymer/DNA particles for drug delivery. The laboratory chose the system, which is equipped with an electron-multiplying CCD high-sensitivity camera and a 404-nm laser, for particle sizing analysis. The nanoparticle tracking analysis yields a direct number-averaged distribution of particle size as well as absolute particle concentration.

A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
