Recent progress on the preparation and surface characteristics of polymeric anti-icing coatings from low energy or liquid-infused slippery surfaces is reviewed illustrated.
Highly transparent antifogging/anti-icing coatings were developed from amphiphilic block copolymers of polyhedral oligomeric silsesquioxane-poly[2-(dimethylamino)ethyl methacrylate]-block-poly(sulfobetaine methacrylate) (POSS-PDMAEMA-b-PSBMA) with a small amount ethylene glycol dimethacrylate (EGDMA) via UV-curing. The excellent antifogging properties the prepared originated hygroscopicity both PDMAEMA and PSBMA blocks in semi-interpenetrating polymer network (SIPN) polymerization EGDMA...
This study investigates the feasibility of characterizing microstructures within a biological tissue by analyzing frequency spectrum photoacoustic signal from tissue. Hypotheses are derived theoretical analyses on relationships between dimensions/concentrations sources region-of-interest and linear model fitted to power spectra signals. The hypotheses validated, following procedures ultrasound analysis, simulations experiments with phantoms fabricated embedding polyethylene microspheres in...
Rapid and accurate detection of changes in glucose (Glu) hydrogen peroxide (H2O2) concentrations is essential for the predictive diagnosis diseases. Electrochemical biosensors exhibiting high sensitivity, reliable selectivity, rapid response provide an advantageous promising solution. A porous two-dimensional conductive metal-organic framework (cMOF), Ni-HHTP (HHTP = 2,3,6,7,10,11-hexahydroxytriphenylene), was prepared by using a one-pot method. Subsequently, it employed to construct...
Diabetic retinopathy (DR), one of the most common microangiopathic complications in diabetes, causes severe visual damage among working-age populations. Retinal vascular endothelial cells, key cell type DR pathogenesis, are responsible for abnormal retinal angiogenesis advanced stages DR. The roles exosomes have been largely unknown. In this study, we report first evidence that derived from vitreous humor patients with proliferative (PDR-exo) promote proliferation, migration, and tube...
Based on the analyzed relationship between microstructure and spectral parameters of photoacoustic signal, a tomography scheme with narrowband low frequency is designed to evaluate subwavelength tissues. Experiments show that this approach can differentiate microstructures two melanomas-like samples, where their structure scales (49 199 μm) are much smaller than working wavelength 0.3–1.5 mm imaging system. Since an effective indicator tissue characteristics, proposed could have potential...
Abstract Conventional gold standard histopathologic diagnosis requires information of both high resolution structural and chemical changes in tissue. Providing optical at ultrasonic resolution, photoacoustic (PA) technique could provide highly sensitive accurate tissue characterization noninvasively the authentic vivo environment, offering a replacement for histopathology. A two-dimensional (2D) physio-chemical spectrogram (PCS) combining micrometer to centimeter morphology composition...
Photoacoustic microscopy (PAM) offers high resolution and 100% sensitivity to optical absorption, making it promising for biomedicine. However, strong light scattering in tissues limits its imaging depth, intensity, resolution. Optical clearing agents (OCA) can reduce scattering. traditional methods often use toxic substances or damage tissue components, restricting their application living tissues. Recently, tartrazine, a common food pigment, has been shown significantly improve...
Vocal fold impact pressures were studied using a self-oscillating finite-element model capable of simulating vocal vibration and airflow. The calculated airflow pressure is applied on the as driving force. region then adjusted according to displacement. interaction between folds produces solution. Lung 0.2 2.5kPa used drive this model. spatial distribution was studied. Studies revealed that tissue collision during phonation very large which correlates with lung glottal width. Larger narrower...
Quantitative detection of stochastic microstructure in turbid media remains a challenge to both optical and acoustical observation. A method photoacoustic spectral matching is proposed solve this problem. This allows us quantitatively detect the characteristic dimension microstructures using long wavelength. Using working wavelength about 375 μm, we accurately measure dimensions (49, 94.8, 199 μm) particles hidden phantoms. Since composed commonly appear tissue, might provide an insight into...
Dental hard tissue lesions, including caries, cracked-tooth, etc., are the most prevalent diseases of people worldwide. lesions and correlative greatly decrease life quality patients throughout their lifetime. It is still to noninvasively detect these dental in early stages. Photoacoustic imaging an emerging hybrid technology combining high spatial resolution ultrasound deep with rich optical contrasts. In this study, a dual-contrast photoacoustic tomography applied lesions. One contrast,...
