Feathers of Autumn

Needles, spherulites, and dendrites are observed in this image of ellipticine, a pharmaceutical used to treat cancer, grown by solution shearing on a polymer substrate. The multitude of crystal morphologies resembles the diversity in color and shape of feathers in autumn. Image coloring slightly enhanced.

Freeform 3D-Printed Heart Scaffold with Gummy Bear

Macro photograph of a vascular template made of a low-calorie sugar substitute. The template is composed of 4,637 filaments, each individually "drawn" by a nozzle translated in 3D space. The template can be coated with a hydrogel then dissolved away, leaving a fully vascularized construct. Gummy bear shown for scale.

Blooms on Graphene

Scanning electron microscope image of a three-dimensionally graphene-sandwiched secondary battery cathode. The fabricated cathode, consisting of an electrically conductive 4~10 layer thick graphene sheet (green color) embedded within electrochemically active vanadium pentoxide (purple color), exhibits a high electrochemical performance including high capacity and long cycling life (>2000 cycles).

A Cell Under Pressure

A human osteosarcoma cell shows large deformations on its basal side, a result of rapid exposure to hyper-osmotic pressure. Actin stress fibrils labelled in green maintain the integrity of the cell, but the endoplasmic reticulum and nucleus (in red) are deformed and pushed upwards. Image taken on a Zeiss Elyra SR-SIM scope.

Contact Guidance of Neuronal Network Through Chemistry

Confocal fluorescence micrograph of primary dorsal root ganglion cells cultured on a Silicon 3D scaffold (inset: light micrograph) coated with a custom cell-adhesive protein. The neurons (red) and supporting glial cells (green) form complex intertwining networks with increased time in culture that abide by the geometric cues of the scaffold.
