Silver mirror reaction as a simple method for silicon nanowires functionalization

A cheap and facile wet-chemical ‘silver mirror’ reaction approach has been proposed for the silicon nanowires (SiNWs), formed by the metal-assisted wet-chemical etching, decoration with silver nanoparticles...

Nonresonant Raman spectroscopy of isolated human retina samples complying with laser safety regulations for in vivo measurements

Retinal diseases, such as age-related macular degeneration, are leading causes of vision impairment, increasing in incidence worldwide due to an aging society. If diagnosed early, most cases could be prevented....

Genotyping of methicillin-resistant Staphylococcus aureus from sepsis patients in Pakistan and detection of antibodies against staphylococcal virulence factors

In order to obtain more information on the MRSA population structure in the border region of Afghanistan and Pakistan, we collected and genotyped MRSA causing bloodstream infections from a tertiary care...

Light guidance in photonic band gap guiding dual-ring light cages implemented by direct laser writing

Efficient waveguiding inside low refractive index media is of key importance for a great variety of applications that demand strong light–matter interaction on small geometric footprints. Here, we demonstrate...

Raman spectroscopic analysis of microbial gas exchange processes

Counterfeit and substandard test of the antimalarial tablet Riamet® by means of Raman hyperspectral multicomponent analysis

The fight against counterfeit pharmaceuticals is a global issue of utmost importance, as failed medication results in millions of deaths every year. Particularly affected are antimalarial tablets. A very...

Characterization of Fuel Gases with Fiber Enhanced Raman Spectroscopy

Common gaseous fuels are mixtures of several components. As the properties of the fuels can vary with the composition, but combustion needs to be stable, reliable analytical methods are highly sought after....

New perspectives for viability studies with high-content analysis Raman spectroscopy (HCA-RS)

Raman spectroscopy has been widely used in clinical and molecular biological studies, providing high chemical specificity without the necessity of labels and with little-to-no sample preparation. However,...

CD19-targeted, Raman tagged gold nanourchins as theranostic agents against acute lymphoblastic leukemia

The incidence of Acute Lymphoblastic Leukemia (ALL) is increasing globally, and it is being clinically addressed by chemotherapy, followed by immunotherapy and stem cell transplantation, all with potential...

Vibrational spectroscopy as a powerful tool to follow-up immunoadsorption therapy treatment of dilated cardiomyopathy – a case report

Dilated cardiomyopathy (DCM) is a leading cardiomyopathy entity and is the leading reason for heart transplantation. Due to high etiologic and genetic heterogeneity of the pathologies, different therapeutic...
