Multifractality in Surface Potential for Cancer Diagnosis

|
By Phat Huynh, Dang Nguyen, Grace Binder, Sharad Ambardar
| ACS Publications
Recent advances in high-resolution biomedical imaging have improved cancer diagnosis, focusing on morphological, electrical, and biochemical properties of cells and tissues, scaling from cell clusters down to the molecular level. Multiscale imaging revealed high complexity that requires advanced data processing methods of multifractal analysis. We performed label-free multiscale imaging of surface potential variations in human ovarian cancer cells using Kelvin probe force microscopy (KPFM).

Point-of-care detection, characterization, and removal of chocolate bloom using a handheld Raman spectrometer

|
By Siyu He, Joshua Heuler, Sharad Ambardar, Dmitri V. Voronine
| Nature Verified
Abstract Chocolate bloom is an off-white coating on the surface of chocolate products due to the altered distribution of the ingredients. Bloom reduces the shelf-life of chocolate and affects its visual and tactile quality, all of which are serious concerns for chocolate manufacturers and consumers. The automated, rapid, and noninvasive point-of-care detection of chocolate bloom has been an essential but challenging problem.
