The main objective of this work was to quantitatively measure the nanotribological properties or organic layers and rationalize them from a physicochemical point of view. To accomplish that, a wide array of samples was ...
Esta Memoria describe la síntesis de nanopartículas de Au y Pd funcionalizadas periféricamente con fragmentos organometálicos. Para ello se sintetizó previamente el nuevo ligando ditópico tiol-fosfina, L, HS(CH2)11OOCC6H4PPh2. ...
El carprofen (CP), es un antiinflamatorio no esteroideo, con actividad antiinflamatoria, analgésica y antipirética, se utiliza en medicina veterinaria para el tratamiento de patologías de origen agudo y crónico, como ...
El objetivo general que se ha planteado en este trabajo de tesis ha sido la obtención de nanopartículas magnéticas (NMPs) que puedan presentar aplicaciones biomédicas. El tipo de NPMs desarrolladas han sido, por una parte, ...
[spa] De entre las vacunas de ácidos nucleicos, las basadas en ARNm autoreplicativos (replicones) o ARNm convencionales unidos a diferentes nanopartículas (NPs) como: oro (Au-NP), nanocápsulas (NCs), ácido poliláctico ...
[cat] La leucèmia mieloide aguda (LMA) és un grup heterogeni de malalties hematològiques que s'originen a partir de la proliferació clonal excessiva de cèl·lules precursores mieloides. Actualment, malgrat que la majoria ...
Davant la necessitat de nous enfocaments en el tractament de determinades malalties, en els darrers anys s’han desenvolupant sistemes nanoestructurats no virals com a vehiculitzadors d’agents terapèutics -entre els que es ...
En aquesta tesi doctoral es descriu la síntesi i la caracterització de nanopartícules homo- i heterometàl•liques, així com la dels seus lligands estabilitzadors. A més, s’estudia el comportament catalític de les nanopartícules ...
The structure and physicochemical properties of biomembranes are fundamental for the functioning of cells, and many pathologies have been associated with their alteration (cancer, neurodegenerations, obesity, etc.) 1, 2. ...
The microwaves electromagnetic properties, i.e. the complex permittivity, of single cells determine how this radiation is transmitted, reflected or absorbed by biological tissues. This information is important for the ...
[eng] Electrolyte-gated transistors (EGTs) have emerged as key platforms for transducing and amplifying biological and biochemical signals, making them an integral part of diverse biosensing and bioelectronic applications ...
Cell membranes are 2-D heterogeneous fluid systems that show nanoscale structures of great interest because of its importance in membrane functions. Due to the inherent complexity of natural membranes, the study of model ...
The ability to characterize the elements beneath the surface has been a dire necessity in the fields of materials science, polymer technology, biology, and medical sciences. Scanning Probe Microscopies are the family of ...
Storing the fluctuating renewable energy into synthetic fuels or in batteries is meaningful due to the emerging energy crisis. In this thesis, four nanostructured catalysts based on two kinds of metal sulfides, namely Cu2S ...
The incidence of neurodegenerative diseases, such as Alzheimer's disease, increases every year due to population aging. Therefore, the development of new therapeutic strategies, such as biodegradable nanostructured systems ...
The skin is major organ of the human body, and its function is to protect the internal tissue from environmental changes, maintains the body temperature and avoid penetration of contaminants. Therefore, the skin barrier ...
Over the recent decades, several studies revealed the precarious climate situation which is threatening all Life forms on earth, including mankind, even if sometimes we tend to ignore the actual fragility of our situation. ...
Despite the latest advances in early diagnosis and increased resources employed to develop new therapeutic options, effective control of cancer disease remains a challenge. In fact, cancer is the second leading cause of ...
[spa] Los CNTs presentan propiedades eléctricas, térmicas y mecánicas singulares que han suscitado un interés considerable en las dos últimas décadas por sus posibles aplicaciones en Ciencia e Ingeniería de Materiales. ...
Cada vez más todas las ciencias se están viendo sujetas a una evolución técnica, inevitable en los tiempos que corren, entre estos avances se incluyen las fuentes audiovisuales. Desde hace ya algún tiempo las ciencias ...
