Imaging intracellular fluorescent proteins at nanometer resolution.

We introduce a method for optically imaging intracellular proteins at nanometer spatial resolution. Numerous sparse subsets of photoactivatable fluorescent protein molecules were activated, localized (to approximately 2 to 25 nanometers), and then bleached. The aggregate position information from all subsets was then assembled into a superresolution image. We used this method--termed photoactiv...

Real-time visualization of clustering and intracellular transport of gold nanoparticles by correlative imaging

Mechanistic understanding of the endocytosis and intracellular trafficking of nanoparticles is essential for designing smart theranostic carriers. Physico-chemical properties, including size, clustering and surface chemistry of nanoparticles regulate their cellular uptake and transport. Significantly, even single nanoparticles could cluster intracellularly, yet their clustering state and subseq...

High resolution imaging of intracellular oxygen concentration by phosphorescence lifetime

Optical methods using phosphorescence quenching by oxygen are suitable for sequential monitoring and non-invasive measurements for oxygen concentration (OC) imaging within cells. Phosphorescence intensity measurement is widely used with phosphorescent dyes. These dyes are ubiquitously but heterogeneously distributed inside the whole cell. The distribution of phosphorescent dye is a major disadv...

High Resolution 3D Intracranial Imaging at 3.0T

Introduction Vessel wall imaging of intracranial arteries is challenging due to their small sizes and their relatively deep locations inside the brain. 3D Time-of-flight (TOF) and contrast enhanced MRA (ceMRA) are commonly used [1] luminographic techniques. They lack specificity as luminal defects may be caused by various reasons. Dark blood, two dimensional turbo spin echo (2DTSE) has been use...

High-Resolution, Low-SAR T2 Imaging at High Magnetic Fields

The PSIF (gradient-reversed FISP, SSFP, CE-FAST) sequence is demonstrated to produce high-quality, T,-weighted images in human brain at magnetic field strengths of 4 Tesla and above In contrast to spin-echo or multiple-echo imaging techniques commonly used in clinical practice at lower fields, the importance of Bi homogeneity in PSIF imaging is minimal and the average RF power deposition is low...
