Two-Photon Polymerization Lithography for Imaging Optics

Optical imaging systems have greatly extended human visual capabilities, enabling the observation and understanding of diverse phenomena. Imaging technologies span a broad spectrum of wavelengths from...

Structured illumination microscopy with extreme ultraviolet pulses

The relentless pursuit of understanding matter at ever-finer scales has pushed optical microscopy to surpass the diffraction limit and produced the super-resolution microscopy which enables visualizing...

Long-Term Stable Organic Solar Cells through Amphiphilic Additives

Organic solar cells have recently experienced tremendous efficiency improvements, but their longevity is still limited by morphological degradation, among other factors. We demonstrate in this work that...

The effects of photoactivated ciprofloxacin and bile acids on biofilms on bile duct catheters

Objectives: This study examined the potential of a novel photoactivatable ciprofloxacin to act against bacterial infections and microbiomes related to biliary diseases. It also evaluated treatment by combining...

Classifcation of human tooth using laser‑induced breakdown spectroscopy combined with machine learning

Identifcation of human sex from cadaver examination is crucial for various felds like forensic odontology and archaeology. Sex recognition can be very challenging if the cadaver is exposed to extreme temperature...

Field curvature reduction in miniaturized high numerical aperture and large field-of-view objective lenses with sub 1 µm lateral resolution

In this paper the development of a miniaturized endoscopic objective lens for various biophotonics applications is presented. While limiting the mechanical dimensions to 2.2 mm diameter and 13 mm total...

Improved antimicrobial activities of Boswellia sacra essential oils nanoencapsulated into hydroxypropyl-beta-cyclodextrins†

Natural antimicrobials have recently gained increasing interest over synthetic antimicrobials to overcome foodborne pathogens and food microbial contamination. Essential oils (EOs) obtained from Boswellia...

Opinions on imaging and cutting-edge developments in light microscopy for biomedical applications

PEtOxylated polyesteramide nanoparticles for the delivery of anti-inflammatory drugs

Poly(ester amide)s (PEAs) consisting of L-valine (Val), glycolic acid (G), and L-isoleucine (Ile), i.e., PValG and PIleG, and various poly(2-ethyl-2-oxazoline)-block-poly(ester amide) copolymers (PEtOx-b-PEA)...

Review of Fluorescence Lifetime Imaging Microscopy (FLIM) Data Analysis Using Machine Learning

Fluorescence lifetime imaging microscopy (FLIM) has emerged as a promising tool for all scientific studies in recent years. However, the utilization of FLIM data requires complex data modeling techniques,...
