Art in Research

Science is an art, but not all scientists are artists.

That said, we purposefully encourage our Biomedical Engineering students to express their creativity while showcasing their research.

Each fall, students submit images—photographs, micrographs, illustrations, visualizations and renderings—depicting their science, along with a description of how the image was created and how it represents the importance of research in their field. Art in Research is intended to be a record of striking visual qualities and a lens into the science, to be shared with fellow researchers and the general public alike.

A Moment in Time

Submitted by: Luke Shinneman

Category: Microscopy

Contributions: Leo Green

Creation: Microbes from the soil in West Lafayette were cultured on the surface of gelatin-halide film prints.

Caption: This photograph was taken on my 1975 Yashica film camera on a trip to the Galápagos Islands of Ecuador. Prior to inkjet printing in the 1990’s, photographs were printed on gelatin-halide emulsions like these. Taking advantage of microbes’ ability to break down and recycle large proteins, we cultured bacteria and fungi from the soil of West Lafayette on the surface of these prints, and captured their final progress in a moment in time..

 

A Purdue logo

Submitted by: Van Thuy Duong

Category: Microscopy

Creation: We attempted to achieve spatially dynamic stiffening and softening within the same dSIS-NB-only (our novel bimaterial) gel using micropatterning with the LumenX bioprinter. A simple Purdue University logo was designed using the TinkerCAD website. The logo consisted of two parts: a larger ‘P’ designated for stiffening and a smaller ‘P’ for softening, which overlaid the larger ‘P’. The pre-formed soft gel was stiffened for 60 seconds with 0.5 mM tartrazine, and the larger ‘P’ appeared on the gel in a darker color. The gel was then washed and incubated with 5 mM Rh-PEGSH (red fluorescent molecules) and 6 mM LAP (photo initiator) before exposure with the smaller ‘P’ for 60seconds with 0.5 mM tartrazine. The smaller ‘P’ overlaid the larger ‘P’ to form a Purdue University logo. The red area was initially soft, then stiffened, and then softened again. The hydrogel was imaged using a 3D fluorescent confocal microscope (BC43) using a 2X objective.

Bloom of the Human Gut Assembloids-on-a-Chip

Submitted by: Jong-Keun Sim

Category: Microscopy

Contributors: Leandra Suter and Estelle Park

Creation: The human assembloids-on-a-chip platform combines stem cell biology with microengineering to generate complex intestinal tissue structures in vitro. By guiding the fusion of multiple human intestinal organoids and exposing them to controlled soluble gradients, the system promotes the emergence of budding morphologies that closely mimic the crypt–villus architecture of the intestine. This innovation allows researchers to model spatial organization and signaling dynamics of the tissue with unprecedented precision, advancing studies in development, disease modeling, and drug discovery.

Caption: A confocal micrograph of a human gut assembloid formed within a microengineered chip. At the base, fluorescently labeled microchannels in red and green highlight the device structure. Above, the fused intestinal organoids form a large budding tissue that mimics the crypt–villus structure, stained with phalloidin (magenta, actin cytoskeleton) and DAPI (green, nuclei). The image resembles a blooming flower, visually capturing how engineered platforms can recreate the budding architecture of the intestine in vitro. Gut assemblage size: 1747 μm. Device dimensions: 25 mm (width) × 32 mm (length) × 9.6 mm (height).

Fracture in a Mouse Bone

Submitted by: Olivia White

Category: Microscopy

Contributors: Rachel Kohler, Katelynn Gallagher, Dyann Segvich, Karthik Rajesh and Joey Wallace

Creation: Scanning Electron Microscopy

Caption: This piece shows the cross-section of a femur from a mouse after fracture toughness testing. In fracture toughness testing, the bone is notched and broken, then imaged using a scanning electron microscope. In this image, the notch is the smooth surface at the bottom of the bone. Stable growth of the crack during testing is represented by the striations in the bone surface, extending from the notch. Measuring the angle from the center of the bone cross-section to the notch edge and to the end of stable crack growth are each measured. These values can then be used to calculate properties of fracture toughness. Fracture toughness measures can help researchers understand how different treatments, diseases, etc., may impact the fracture resistance of a bone.

Cellular Symphony on Hydrogel

Submitted by: Tuba Marjan

Category: Microscopy

Creation: I created this image using fluorescent microscopy to capture mesenchymal stem cells growing on a 2D hydrogel scaffold. The cells were stained with phalloidin that binds to actin filaments which form the internal structure and give shape to the cell causing them to glow bright red. The nuclei were stained with Hoechst making them glow blue. The hydrogel allowed cells to adhere and spread out. This process blends scientific observation with a visual appreciation of cellular architecture where function meets form in a dynamic expression of life.

Highway to the brain

Submitted by: Sergio Martin

Category: Anatomy & Physiology

Contributors: Thejas Vishnu Ramesh

Creation: This render was created from 4D Flow MRI data acquired at the Purdue 3T GE Discovery MR750 scanner. To obtain blood flow of the carotid bifurcation, a custom-made wearable coil was used. 4D flow MRI enables three-directional measurement of blood flow velocities over the cardiac cycle. Streamlines were generated from the MRI velocity field with the software Paraview, and overlaid over the structural image, acquired with time-of-flight MRI.

Caption: The image shows the flow of blood at the right carotid artery bifurcation. This section of the carotid splits from the common carotid artery into the internal and external carotid arteries, supplying blood to the brain, face, and head. 4D flow MRI can measure blood circulation in vivo, and it can be especially useful to assess vascular health and diseases. Custom-made coils for the neck result in a higher signal, improving the acquisitions of flow and resulting in more accurate velocity fields.

Nuclear pore complexes under super-resolution microscope

Submitted by: Hao-Cheng Gao

Category: Microscopy

Contributors: Fan Xu

Creation: Immunolabeled cells was imaged with 4Pi single-molecule localization microscopy (4Pi-SMLM) and reconstruct its ultrastructure with nanometer resolution by using 4Pi-BRAINSPOT platform.

Caption: Nuclear pore complexes are massive protein assemblies embedded in the nuclear envelope that regulate the bidirectional transport of molecules between the nucleus and cytoplasm, playing a crucial role in cellular function and gene expression. Single-molecule localization microscopy (SMLM) surpasses the diffraction limit by precisely determining the positions of individual fluorophores, while 4Pi microscopy enhances achievable resolution through interferometric optical design. Together, 4Pi-SMLM facilitates 3D imaging of proteins with nanometer precision. The color code represents the depth (Z position) of the Nup96 proteins, as indicated by the color bar.

Starry Night, Cell-estial Edition

Submitted by: Claudia Benito Alston

Category: Microscopy

Contributors: Michael Deines, Madison Howard & Evelyn Nonamaker

Creation: I cultured bone Messenchymal Stem Cells (bMSCs) for 14 days, after which I fixed and stained them with an Alkaline Phosphatase labeling kit.

Caption: Staining cells with alkaline phosphatase (ALP) is commonly used to assess cell differentiation, particularly in studies involving osteogenic (bone-forming) cells. ALP is an early marker of osteoblast differentiation, meaning it is expressed when precursor cells begin to differentiate into bone-forming osteoblasts. By staining cells for ALP, we can visually confirm and quantify the activity of these cells as they progress along the osteogenic pathway.
