Bromine indirubin FLIM/PLIM sensors to measure oxygen in normoxic and hypoxic PDT conditions

open access: yesPhotodiagnosis and Photodynamic Therapy
Background: The induction of phototoxicity during photodynamic therapy (PDT) is dependent on oxygen availability. For this reason, the development of sensors to measure oxygen and oxygen consumption is extremely important.

Monitoring and Maintaining Laser Surface Texture Quality Based on Acoustic and Optical Process Emissions during Direct Laser Interference Patterning

open access: yesAdvanced Engineering Materials, EarlyView.
Acoustic emissions during direct laser interference patterning are shown to strongly correlate with surface texture depth. By implementing a closed‐loop control system utilizing acoustic feedback, consistent microstructures with uniform depth are achieved despite laser power fluctuations.

Intratumoral Cancer Cell Intravasation Can Occur Independent of Invasion into the Adjacent Stroma

open access: yesCell Reports, 2017
Summary: Intravasation, active entry of cancer cells into the circulation, is often considered to be a relatively late event in tumor development occurring after stromal invasion. Here, we provide evidence that intravasation can be initiated early during

Biological confocal microscopy

open access: yesMaterials Today, 2002
Abstract The first practical use of confocal optics was by Hiroto Naora1, 1 , 2 , who built a device based upon a theoretical concept devised by his supervisor Z. Koana 3 , over 50 years ago. His system did not form images, but was used in high resolution micro-spectrophotometry.

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

open access: yesAdvanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

A temperature-controlled stage for laser scanning confocal microscopy and case studies in chemistry of materials [PDF]

open access: yesarXiv, 2017
If confocal microscopy is an ubiquitous tool in life science, its applications in chemistry and materials science are still, in comparison, very limited. Of particular interest in these domains is the use of confocal microscopy to investigate temperature-dependent phenomena such as self-assembly, diffusio- or thermophoresis, or crystal growth.

Confocal microscopy and exfoliative cytology

open access: yesJournal of Oral and Maxillofacial Pathology, 2013
Early detection of potentially malignant lesions and invasive squamous-cell carcinoma in the oral cavity could be greatly improved through techniques that permit visualization of subtle cellular changes indicative of the neoplastic transformation process. One such technique is confocal microscopy. Combining rapidity with reliability, an innovative idea
