Simplified method for calibrating optical tweezers

Broadband measurement of viscoelasticity with reduced measurement time

20-Jul-2021 - Measurements of biomechanical properties inside living cells require minimally invasive methods. Optical tweezers are particularly attractive as a tool. It uses the momentum of light to trap and manipulate micro- or nanoscale particles. A team of researchers led by Prof. Dr. Cornelia Denz from ...

Don't Give the Slightest Chance to Toxic Elements in Medicinal Products

New high-accuracy reference solutions for the SI-traceable measurement

27-Mar-2018 - Lead, cadmium, mercury, and arsenic do not belong in medicinal products. International requirements for the quality of medicines have therefore become more stringent and introduced new control requirements. Hence, it makes sense to use high-accuracy reference solutions with defined contents of ...

Harvard researchers define 'good' stem cells

Establishing standards where none exist

10-Mar-2014 - After more than a decade of incremental – and paradigm shifting, advances in stem cell biology, almost anyone with a basic understanding of life sciences knows that stem cells are the basic form of cell from which all specialized cells, and eventually organs and body parts, derive. But what makes ...

Calibration tools to encourage use of novel medical imaging technique

10-Dec-2013 - The National Institute of Standards and Technology (NIST) has developed prototype calibration tools for an experimental medical imaging technique that offers new advantages in diagnosing and monitoring of certain cancers and possibly other medical conditions. NIST designed, constructed and tested ...
