Hyaluronic Acid‐Based, Double Network Hydrogels With Tunable Viscoelasticity for Neural Cell Culture
Journal of Biomedical Materials Research Part A, Volume 114, Issue 2, February 2026.ABSTRACT Brain tissue is the softest, most viscoelastic tissue in mammals and these mechanical properties strongly influence cell phenotypes. However, conventional hydrogels for 3D cultures rarely provide the ability to tune the elasticity (G′) independently of the viscosity (G″), making it impossible to decouple the effects of each mechanical ...

International Journal of Climatology, Volume 46, Issue 2, February 2026.The CliDaR‐Africa project engages undergraduates in digitising historical African weather records, rescuing over 300,000 observations from Madagascar and the Central African Republic (1949–1966). Analysis of the Madagascar data reveals overlooked extreme events, including a sequence of tropical cyclones, highlighting the country's vulnerability to ...

Small, Volume 22, Issue 7, 2 February 2026.A composite hydrogel (C‐gel) incorporating PEG‐b‐PPS filomicelles enables localized in situ gelation and sustained nanocarrier release within the anterior chamber. The filamentous structure promotes spatial confinement of multi‐arm polymer crosslinking, even upon injection into large aqueous volumes, and gradually transitions into spherical micelles ...

Swept source-OCT and swept source-OCT angiography findings in posterior microphthalmos
International Ophthalmology, 2019To describe swept source-OCT (SS-OCT) and swept source-OCT angiography (SS-OCTA) findings in eyes with posterior microphthalmos (PM).Twelve eyes (six patients) with PM were evaluated using SS-OCT and SS-OCTA. Structural changes, subfoveal choroidal thickness (SFCT), and perifoveal capillary changes with qualitative and quantitative assessments were ...

Swept-source OCT and swept-source OCT angiography in glaucoma diagnostics
Spektrum der Augenheilkunde, 2017Swept-source OCT (SS-OCT) has been introduced as a fast method for examining the retinal nerve fiber layer (RNFL) and, like OCT angiography (OCTA), the structure of vessels in the retina and the optic nerve head. The aim of this study was to assess whether SS-OCT is able to detect different patterns of glaucomatous nerve fiber layer defects and to ...

SPIE Proceedings, 2009
By increasing the speed and reducing the complexity of OCT systems, the parallel OCT system presented here will reduce the cost of high performance instruments while making them more widespread and easy to use. The instrument integrates line scanning with a swept source to achieve ultrahigh image speeds in a much simpler way.

Towards swept-source mid-infrared OCT
Biophotonics: Photonic Solutions for Better Health Care VI, 2018A swept-source optical coherence tomography (OCT) system is demonstrated in the mid-infrared region. A Michelson interferometric setup is illuminated by an external cavity quantum cascade laser (QCL), with a scanning frequency of 1 Hz. A-scans were collected using three different samples: a mirror, CaF2 coated with germanium on both of its surfaces ...

Glaucoma is a leading cause of blindness worldwide [1]. It is defined as a group of progressive optic neuropathies with characteristic retinal ganglion cell damage at the optic disc and a concomitant pattern of visual field loss [2]. Structural measurements have become more important for glaucoma diagnosis and follow-up.

Introduction to Swept Source OCT
2017Optical coherence tomography (OCT), first introduced in 1991, is an enabling optical, noninvasive imaging modality that provides cross-sectional visualization of biological tissues with resolutions one to two orders of magnitude better than conventional ultrasound [1].
