Vibrational spectroscopies provide information about the biochemical and structural environment of molecular functional groups inside samples. Over past few decades, Raman infrared-absorption-based techniques have been extensively used to investigate biological materials under different pathological conditions. Interesting results obtained, so these proposed for use in a clinical setting diagnostic purposes, as complementary tools conventional cytological histological techniques. In most...
Abstract Background The management of cutaneous metastases often represents a challenge because they may be widespread and recur after radiotherapy or chemotherapy; breast cancer accounts for 51% the total cases metastases. When surgical excision chest wall recurrences is not possible other local treatments such as with hyperthermia fail, topical chemotherapy electrochemotherapy (ECT) might taken into account. ECT new treatment solid tumors which can defined potentiation, by means...
Colorectal cancer is one of the most commonly diagnosed cancers in developed countries. Although gold-standard diagnosis technique histological analysis colon biopsies, it important to investigate different diagnostic tools because microscope examination stained tissues provides indications partially depending on experience pathologist. This study reports a Raman-spectroscopy-based healthy and cancerous cells detect biochemical differences at subcellular level discriminate former from...

A micro-Raman spectroscopy investigation has been performed in vitro on single human mammary epithelial cells after irradiation by graded x-ray doses. The analysis principal component (PCA) and interval-PCA (i-PCA) methods allowed us to point out the small differences Raman spectra induced irradiation. This experimental approach enabled delineate radiation-induced changes protein, nucleic acid, lipid, carbohydrate content. In particular, dose dependence of PCA i-PCA components analyzed. Our...
Eumelanin biopolymer synthetized from L-DOPA has been characterized by Raman and Surface Enhanced Spectroscopy (SERS). Although spectra of eumelanin were scarcely resolved, SERS measurements this on nanostructured gold substrate, provided a large enhancement vibrational peaks related to functional groups adherent the so that well resolved obtained. The correspond modes monomeric units eumelanin. So, can be used identify content resolve presence which have calculated predicted according...
Abstract We report vibrational spectra of two types eumelanin samples: a synthetic one, produced by oxidation tyrosine with hydrogen peroxide, and natural extracted from Sepia officinalis , the aim pointing out differences between main properties such pigments. Fourier transform infrared, Raman surface‐enhanced scattering allow identification several modes involving specific monomeric units. The are related to (i) larger amount carboxylic acid in than sample; (ii) shift spectral position...
Demonstrated is the first example of dihydroxyindole carboxylic acid presence within an insect eumelanin, a conductive biomaterial material for circular economy.

A remote N2–H2 (a mixture of 97% N2–3% H2) rf plasma nitridation procedure has been developed to form a very thin (∼5Å) GaN layer successful in the electronic and chemical passivation GaAs (100) surfaces. The interaction with surface controlled situ real time by spectroscopic ellipsometry. stability is demonstrated nonoxidation nondecaying behavior photoluminescence efficiency passivated over months air exposure.
A mild wet nitridation procedure using hydrazine-based solutions has been developed for GaAs (100) surface passivation. Both x-ray photoelectron spectroscopy and spectroscopic ellipsometry show that this results in a very thin, coherent, homogeneous GaN layer is stable air. Photoluminescence data strong enhancement of the intensity as compared to an as-cleaned sample, indicating nitrided provides both chemical electronic passivation surfaces. The mechanism discussed.
