Effective Photon Count Estimation from a Single Image Acquisition

Most image sensors do not directly report the actual number of detected photons per pixel, but instead a value generated after the photo-electrons registered on a physical sensor have passed through an...

Electrically Excited Plasmonic Nanoruler for biomolecule detection

Plasmon based sensors are excellent tools for a label free detection of small biomolecules. An interesting group of such sensors are plasmonic nanorulers which relay on the plasmon hybridization upon modification...

Beyond endoscopic assessment in inflammatory bowel disease: real-time histology of disease activity by non-linear multimodal imaging

Assessing disease activity is a prerequisite for an adequate treatment of inflammatory bowel diseases (IBD) such as Crohn’s disease and ulcerative colitis. In addition to endoscopic mucosal healing,...

Photo-Induced or Plasmon-Induced Reaction: Investigation of the Light-Induced Azo-Coupling of Amino Groups

The plasmon-mediated azo-coupling of p-aminothiophenol (PATP) and p-nitrothiophenol (pNTP) was recently achieved using gold and silver nanostructures with the help of hot electrons. To further investigate...

Toward Single Electron Nanoelectronics Using Self-Assembled DNA Structure

DNA based structures offer an adaptable and robust way to develop customized nanostructures for various bionanotechnological purposes. One main aim in this field is to develop a DNA nano-breadboard for...

Towards an improvement of model transferability for Raman spectroscopy in biological applications

One of the most important issues for the application of Ramanspectroscopy for biological diagnostics is how to deal efficiently with large datasets. The best solution is chemometrics, where statistical...

Secondary structure and glycosylation of mucus glycoproteins by raman spectroscopies

The major structural components of protective mucus hydrogels on mucosal surfaces are the secreted polymeric gel-forming mucins. The very high molecular weight and extensive O-glycosylation of gel-forming...

Excitation energy dependent ultrafast luminescence behavior of CdS nanostructures

Cadmium sulfide (CdS) nanostructures were excited under ambient conditions by femtosecond (fs) laser pulses (380 nm<lambda_ex < 440 nm, tau=50 fs, rep. rate = 1 kHz, fluence<6.7 mJ/cm2). Their...

Controlling Electronic Transitions in Fullerene van der Waals Aggregates via Supra-Molecular Assembly

Morphologies crucially determine the optoelectronic properties of organic semiconductors. Therefore, hierarchical and supra-molecular approaches have been developed for targeted design of supramolecular...
