Creating Order From Disorder
Light scattering makes clear imaging through an opaque material seem insurmountable, but researchers have discovered that the resulting speckle pattern actually contains the key to restoring the shape of the original object. The findings could have important applications in bioimaging. The speckle pattern “is not completely random but contains some subtle correlations. We realized that the knowledge that these correlations are present was enough to get some information on the object,” Dr. Jacopo Bertolotti of the University of Twente’s MESA+ Institute for Nanotechnology told BioPhotonics. |

Laser Device Images, Tracks Cells, Dye-free
Without contrast dyes or fluorophores, a new device can image and track living cells’ reactions to various stimuli and create 3-D images of biological tissue at the nanoscale in just minutes. The system combines holographic microscopy and computational image processing to obtain 3-D images of living cells from every angle at a resolution of less than 100 nm. Because the tissue can be imaged without using contrast dyes or fluorescents, foreign substances will not distort the experimental results. |

3-D Stress Map Reveals Embryonic Heart Defects
Stresses induced in an embryonic heart by blood flow have been visualized for the first time in 3-D using an optical coherence tomography (OCT) method. The technique could provide new insight into how and why heart defects develop. |

Laser Technique Unravels Spider Silk's Mysteries
A noninvasive, noncontact laser light scattering technique may be the key to unraveling the secret behind spider silk’s strength. Although spider silk is an exceptional biological polymer, it is more complex in structure than its kin, collagen (the stuff of skin and bones), scientists say. |
