Polarization‐Sensitive Holotomography for Multidimensional Label‐Free Imaging and Characterization of Lipid Droplets in Cancer Cells

open access: yesAdvanced Science, EarlyView.
Polarization‐sensitive holotomography (PS‐HT) enables label‐free 3D imaging and quantitative analysis of lipid droplets by exploiting their intrinsic birefringence. Applied to prostate cell models, PS‐HT reveals glucose‐induced lipid accumulation in cancer cells and achieves near‐perfect classification of healthy and cancerous states.

Aging as a Loss of Goal‐Directedness: An Evolutionary Simulation and Analysis Unifying Regeneration with Anatomical Rejuvenation

open access: yesAdvanced Science, EarlyView.
The paper proposes that the root cause of aging is the loss of anatomical goal‐directedness after development. Using evolutionary neural cellular automata simulations, the authors show that after the organism has reached its developmental homeostatic setpoint (the adult morphology), the absence of target state to pursue leads to a drifting anatomical ...

Ultrafast Dynamic Defect Inspection With Computational Neuromorphic Imaging

open access: yesAdvanced Science, EarlyView.
Computational neuromorphic imaging (CNI) is leveraged for ultrafast dynamic defect inspection, offering unparalleled capabilities for fast‐moving samples, complex illumination conditions, and real‐time edge detection. The CNI paradigm will enhance our set of inspection tools in challenging environments, paving the way for intelligent, precise, and low ...

Quantification of Antibiotic Diffusion in Biofilms Using Gold Nanostar Surface‐enhanced Raman Spectroscopy

open access: yesAdvanced Science, EarlyView.
Gold nanostar‐enhanced Raman spectroscopy (SERS) enables real‐time, label‐free tracking of levofloxacin diffusion in intact biofilms. Nanostars embedded 16 µm below the surface detect drug arrival over time, revealing the impact of the biofilm matrix on antibiotic transport. Abstract The increased resistance to antibiotics shown by bacteria in biofilms
