SERS‐Based Nano‐ and Microsystems Toward Biomedical Applications

Small, EarlyView.
This review provides a current overview of nano‐ and microscale SERS‐based devices, encompassing all aspects from material design to practical applications. We highlight controlled SERS‐active architectures, including patterned substrates, nanorods, microspheres, micromotors, and microneedles, as well as combinations of these microfluidic systems.

Calculation and optical measurement of laser trapping forces on non-spherical particles [PDF]

, 2001
Optical trapping, where microscopic particles are trapped and manipulated by light is a powerful and widespread technique, with the single-beam gradient trap (also known as optical tweezers) in use for a large number of biological and other applications.

Training Program for the Use of Magnification Loupes in Dentistry

European Journal of Dental Education, EarlyView.
ABSTRACT Introduction Although magnification loupes offer well‐documented advantages, their initial adaptation can be challenging, often deterring widespread adoption. Without sufficient training during this critical period, students may feel inadequately prepared, limiting their ability to benefit from loupes and contributing to reluctance in their ...

Fatigue behaviour of root filled teeth: The role of endodontic sealers and restorative techniques

European Journal of Oral Sciences, EarlyView.
Abstract This in vitro study aimed to evaluate the fatigue behaviour of root canal treated teeth, filled with either AH Plus Jet (AHP) or AH Plus Bioceramic Sealer (AHPB) and rehabilitated with either mesio‐occlusal‐distal (MOD) restorations (direct resin composite) or endocrowns (indirect resin composite).

Endoscopic Optical Coherence Tomography for Clinical Gastroenterology [PDF]

, 2018
Optical coherence tomography (OCT) is a real-time optical imaging technique that is similar in principle to ultrasonography, but employs light instead of sound waves and allows depth-resolved images with near-microscopic resolution. Endoscopic OCT allows

Cilia in Nervous System Development, Function, and Disease

MedComm – Future Medicine, Volume 5, Issue 2, June 2026.
Cilia are evolutionarily conserved organelles that function as essential sensory and motility platforms in the nervous system. This review outlines key cilia‐dependent signaling pathways and their roles in neural development and function. Furthermore, it highlights how ciliary dysfunction can lead to a variety of neurological disorders, known as ...
