Microscopie Raman stimulée (CARS) : Principes et applications [PDF]

open access: yesmédecine/sciences, 2006
Les avancees recentes en physique des lasers ont permis de mettre en oeuvre une technique de microscopie permettant d’observer les liaisons chimiques des molecules presentes dans un echantillon biologique. Cette technique utilise l’effet Raman stimule comme origine de contraste et permet de generer des images en trois dimensions a partir d’echantillons

Confocal Raman data analysis enables identifying apoptosis of MCF-7 cells caused by anticancer drug paclitaxel [PDF]

open access: yes, 2013
Confocal Raman microscopy is a noninvasive, label-free imaging technique used to study apoptosis of live MCF-7 cells. The images are based on Raman spectra of cells components, and their apoptosis is monitored through diffusion of cytochrome c in ...

Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution

open access: yesAdvanced Engineering Materials, EarlyView.
Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability

Accumulation of Spherical Microplastics in Earthworms Tissues-Mapping Using Raman Microscopy

open access: yesApplied Sciences
The presence of microplastics in the environment is now becoming a challenge for many scientific disciplines. Molecular diversity and spatial migration make it difficult to find plastic-free areas.

Chemical Self Assembly of Graphene Sheets [PDF]

open access: yes, 2009
Chemically derived graphene sheets were found to self-assemble onto patterned gold structures via electrostatic interactions between noncovalent functional groups on GS and gold. This afforded regular arrays of single graphene sheets on large substrates,
