Challenges in carrier‐mediated intracellular delivery: moving beyond endosomal barriers
The deployment of molecular to microscale carriers for intracellular delivery has tremendous potential for biology and medicine, especially for in vivo therapies. The field remains limited, however, by a poor understanding of how carriers gain access to the cell interior. In this review, we provide an overview of the different types of carriers, their speculated modes of entry, putative pathways of vesicular transport, and sites of endosomal escape. We compare this alongside pertinent examples from the cell biology of how viruses, bacteria, and their effectors enter cells and escape endosomal confinement. We anticipate ins...

Osteogenic growth peptide and its use as a bio‐conjugate in regenerative medicine applications
For nearly 2000 years, biomaterials have been used as damaged tissue implants. A field that started with wood and gold tissue replacements has evolved into an advanced science which combines ideas of cellular biology, engineering, and synthetic chemistry to produce bioresorbable materials capable of directing specific cell responses. With the overwhelming number of failed bone defect repairs every year, bone tissue engineering has become an important area of study. Both naturally occurring and synthetic polymeric materials have shown promising results for bone regeneration with their wide range of mechanical and degradatio...

Temporal flickering of contrast agents for enhanced optical imaging: a review
The temporal flickering of contrast agents that labels a biological sample is a unique modality for cellular imaging with single molecule sensitivity. It improves the signal‐to‐noise ratio statistics associated with the noisy in vivo environment and has promising applications in single particle tracking and super‐resolution microscopy techniques. The flickering can be triggered either statistically through the mechanism of temporal fluctuations of the emitter or through external modulation. The enriching toolbox of contrast agents that are feasible for biomedical imaging for the flickering methods will be discussed, ...
