This review covers advances in electrochemical and biochem-ical sensor development and
usage during 2010 and 2011. In choosing scholarly articles to contribute to this review …

Mechanical interactions are fundamental to biology. Mechanical forces of chemical origin
determine motility and adhesion on the cellular scale, and govern transport and affinity on …

Multiple scattering limits the contrast in optical imaging of thick specimens. Here, we present
gradient light interference microscopy (GLIM) to extract three-dimensional information from …

A cellular-level study of the pathophysiology is crucial for understanding the mechanisms
behind human diseases. Recent advances in quantitative phase imaging (QPI) techniques …

An adult animal consists of cells of vastly different size and activity, but the regulation of cell
size remains poorly understood. Recent studies uncovering some of the signaling pathways …

The widespread misuse of drugs has increased the number of multiresistant bacteria, and
this means that tools that can rapidly detect and characterize bacterial response to …

Despite decades of research, how mammalian cell size is controlled remains unclear
because of the difficulty of directly measuring growth at the single-cell level. Here we report …

Determining the growth patterns of single cells offers answers to some of the most elusive
questions in contemporary cell biology: how cell growth is regulated and how cell size …

Cell mass, volume and growth rate are tightly controlled biophysical parameters in cellular
development and homeostasis, and pathological cell growth defines cancer in metazoans …

Developing microscale sensors capable of force measurements down to the scale of
piconewtons is of fundamental importance for a wide range of applications. To date …
