SEM Studies on Unmanageable Hair.

CL-SEM for studies on cellular components and infection

In the last years, the combination of different imaging modalities, in particular fluorescence optical light microscopy (FLM) and electron microscopy (EM) techniques, became one of the main challenges. Correlative Light Electron Microscopy (CLEM) methods allow to bridge the resolution gap between ultrastrucural studies and dynamic, functional analysis in cellular systems. Recent advances in lig...

AFM, SEM and TEM Studies on Porous Anodic Alumina

Porous anodic alumina (PAA) has been intensively studied in past decade due to its applications for fabricating nanostructured materials. Since PAA's pore diameter, thickness and shape vary too much, a systematical study on the methods of morphology characterization is meaningful and essential for its proper development and utilization. In this paper, we present detailed AFM, SEM and TEM studie...

Morphological Analysis of Polymers on Hair Fibers by SEM and AFM

The polyquaternium 7 polymer is widely used in cosmetic formulations. Morphologic alterations in hair fibers were observed after the application of the polyquaternium 7 polymer, using SEM and AFM. Continuous applications of this product indicated that it accumulates on the fibers, improving the aspect of the hair surface. Quantitative analysis of the images obtained by AFM was undertaken. The...

Human Hair Studies: III. Refractive Index of Crown Hair

New studies on hair cell regeneration in birds

The discovery of hair cell regeneration in birds a little over a decade ago raises a number of obvious and exciting questions about basic functional and neural plasticity in the vertebrate auditory system. Because many birds must learn the complex, species-specific, acoustic signals they use for communication just as humans must learn the sounds of speech, the finding of hair cell regeneration ...
