Monte Carlo Analysis of Optical Interactions in Reflectance and Transmittance Finger Photoplethysmography [PDF]

open access: yes, 2019
Photoplethysmography (PPG) is a non-invasive photometric technique that measures the volume changes in arterial blood. Recent studies have reported limitations in developing and optimising PPG-based sensing technologies due to unavailability of the ...

A Randomized Single‐Center Proof of Principle Study to Evaluate the Effectiveness and Safety of a Hydrogel Laser Treatment Patch in Laser Hair Removal

open access: yesLasers in Surgery and Medicine, EarlyView.
ABSTRACT Background Laser hair removal (LHR) is a commonly performed aesthetic procedure known to generate a hazardous laser plume composed of toxic chemicals, ultrafine particles, and potentially infectious biological materials. Current mitigation strategies, such as smoke evacuation systems, are costly and often used inconsistently, highlighting the ...

Deposition Mechanism and Properties of Thin Polydopamine Films for High Added Value Applications in Surface Science at the Nanoscale [PDF]

open access: yes, 2016
Polydopamine films have been introduced by Messersmith et al. as a possible “versatile” surface functionalization method allowing to coat the surface of almost all known materials even superhydrophobic surfaces.

Boron‐10 carriers and their applications in boron neutron capture therapy

open access: yesPrecision Radiation Oncology, EarlyView.
Summary of different types of boron drugs. Abstract Boron neutron capture therapy (BNCT) has emerged as a promising therapeutic modality in cancer treatment, demonstrating the ability to selectively eliminate cancer cells through the 10B(n,α)7Li nuclear reaction with minimal side effects on normal tissues.

The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

open access: yesResponsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

Staging concept for aging management: Definition, mechanism, and coping strategies

open access: yesVIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...
