Laser induced breakdown spectroscopy (LIBS) can be used to determine solid, liquid, colloidal, and biological samples. It is a promising technique for analysis and characterization of the composition of a broad variety of objects. This review describes in brief the basic principles and technological aspects of LIBS, and the most recent progress of the various applications of this technique in b...

Raman spectroscopy is a valuable analytical technique for the identification of biomolecules and minerals in natural samples, which involves little or minimal sample manipulation. In this paper, we evaluate the advantages and disadvantages of this technique applied to the study of extremophiles. Furthermore, we provide a review of the results published, up to the present point in time, of the b...

The influence of a bio-decontaminating atmospheric pressure plasma (1.1 MHz, Ar/O2), on the physicochemical surface properties of medical polymers is investigated. The plasma exposure results in the incorporation of oxygen which, in turn, leads to the formation of oxygen-containing groups and in changes in surface roughnesses. Furthermore, it is observed that the modification of the polymers oc...

ABSTRACT This work presents the novel glass nanopillar array based nanoplasmonic lab-on-a-chip for highly sensitive surface-enhanced Raman Spectroscopy (SERS). In this work, large-area glass nanopillar arrays are fabricated on both sides of the wafers by combination of metal dewetting and reactive-ion-etching (RIE) process. Metal layer is deposited onto one side to construct nanoplasmonic biose...

INtroductIoN: Treatment goal in cutaneous squamous cell carcinoma (SCC) is complete removal of the tumor with clear histological margins. Gold nanoparticles (GNPs) can be distributed to a tumor by conjugating them with an antibody specific to the tumor’s surface receptor. The consequent change in the optical properties of the cancerous tissue distinguishes it from normal tissue. Given that abou...

Recently, there has been a significant interest in employing Terahertz (THz) technology, spectroscopy and imaging for standoff detection applications. There are three prime motivations for this interest: (a) THz radiation can detect concealed weapons since many non-metallic, non-polar materials are transparent to THz radiation, (b) target compounds such as explosives, and bio/chemical weapons h...
