Inner Quartz Plasma Tube

Particles were found on the wafer surfaces inline after a plasma was generated through this quartz tube. I cracked open the tube and found how the plasma was etching into the quartz, revealing these structures that would eventually thin enough to break off and land on the wafer.

Swollen particles of porcine gelatin and water soluble natural dye

Porcine gelatin containing natural dye developed to increase the potential application of natural dyes in powder for preparation of desserts, drinks, jelly beans, confectionery, in order to make these healthier food products and reduce the consumption of artificial dyes directly related to toxicological problems to human health. The image shows the high power particles present to absorb moisture and become swollen.

Crazing of Paint

An area of Pt thin film deposited on the surface of a polished fine grained sample. Subjected to tensile mechanical stress, substrate and thin film show a different plastic behavior. Mixed together and material information was obtained by the use of the solid state below the lens detector in addition to beam deceleration.

Association of cancer and myeloid cells

Immune surveillance by macrophages and monocytes is important for removing foreign invaders from the body, eliminating dead or damaged cells, and tissue homeostasis. Functional plasticity of macrophages enables them to respond to different stimuli, performing a variety of immune modulatory roles. During tumor development, macrophages are among the first immune cells to migrate into the tumor. Stimuli, including molecules secreted by cancer cells, polarize macrophages into various tumor-associated macrophage subpopulations. Factors secreted by macrophages include immunosuppressive cytokines, inflammatory chemokines, and phagocytosis molecules. Shown here are multiple macrophages (white) associating with a breast cancer cell (red). At the University of New Mexico, we are using nanotechnology to deliver agents that influence immune cells to actively participate in destroying tumor cells.
