Therapy-induced senescent (TIS) cells are cancer cells that become resistant to therapies and enter a dormant stage. These cells can emerge from dormancy and induce tumor resistance and relapse. To provide insight into how TIS cells evolve, it is crucial to develop simple, reproducible methods to study the onset and progression of these cells in human cancer cell cultures.

An international team from Johns Hopkins University and Italy’s Politecnico di Milano, Fondazione Istituto Nazionale dei Tumori, and Consiglio Nazionale delle Ricerche developed a noninvasive, multimodal imaging technique to allow early identification of TIS cells. The new technique could improve clinical outcomes by enabling more comprehensive research into...]]> https://www.photonics.com/Articles/Microscopy_Methods_Combine_to_Detect/a69380 A69380 Mon, 09 Oct 2023 07:00:00 GMT
Postpartum hemorrhage, the leading and most preventable cause of maternal mortality, can be hard to detect, because physiological compensation mechanisms can mask excessive bleeding. In the early stages of hemorrhage, the sympathetic nervous system becomes activated to ensure adequate perfusion of vital organs and, in turn, vital signs remain stable.

Worldwide, the most common methods of diagnosing postpartum hemorrhage are visual estimation of blood loss or monitoring of vital signs. Blood loss is routinely underestimated beyond the point of early intervention.

To diagnose postpartum hemorrhage in its early stages, a multidisciplinary research team at Washington University in St. Louis developed a wearable optical device that...]]> https://www.photonics.com/Articles/Wearable_Sensor_Could_Lower_Mortality_Due_to/a69365 A69365 Tue, 03 Oct 2023 07:00:00 GMT

With the development of a single-layer, blue-emitting OLED, researchers at the Max Planck Institute (MPI) for Polymer Research demonstrated that one-layer OLEDs can achieve a performance level comparable to commercial OLEDs with multiple layers, while simplifying OLED design, fabrication, and analysis.

Early OLEDs had a simple device structure. A semiconducting layer was sandwiched between two electrodes. Holes were injected into the organic semiconductor layer via the anode, and electrons via the cathode. Since then, considerable efficiency gains have been made by increasing the number of functional layers in OLEDs.

However, multilayer OLEDs are complex to design and fabricate. The need for additional fabrication steps can...]]> https://www.photonics.com/Articles/Single-Layer_OLED_Design_Offers_Efficiency/a69361 A69361 Thu, 28 Sep 2023 07:00:00 GMT https://www.photonics.com/Articles/Photonis_Group_Rebrands_as_EXOSENS/a69358 A69358 Wed, 27 Sep 2023 07:00:00 GMT

The ability to measure the size and color of the light at the same time could improve a crucial step in chipmaking — lithography — by enabling lithography machines to make smaller, faster chips. To produce the microsize chips used in most electronic devices, lithography machines need precision-engineered lenses, mirrors, and light sources.

A multispectral, super-low-dose photoacoustic microscopy (SLD-PAM) system developed by City University of Hong Kong (CUHK) achieves significantly higher sensitivity than traditional optical resolution photoacoustic imaging.

By providing an exceptionally high level of sensitivity, SLD-PAM could help broaden the use of photoacoustic microscopy in biomedical applications. In the future, it could translate to clinical settings; for example, it could be used for ophthalmic exams where a low-power laser is preferred for the patient’s safety and comfort. Long-term monitoring of pharmacokinetics or blood flow also requires low-dose imaging to alleviate perturbation to tissue function.

Researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) have created a detection system that allows home energy auditors to see air leaking from a building in real time with the help of a camera. This could provide more accurate readings far more quickly than current diagnostic tools allow.

As leaky buildings signal dwindling energy efficiency and higher utility bills to homeowners, auditors must be called in to figure out where those leaks are. Solving the problem means pinpointing exactly where air is escaping so that cracks can be sealed, but this process can be expensive, time-consuming, and cumbersome.

Traditionally, blower-door testing would be used to detect leaks in conjunction with smoke....]]> https://www.photonics.com/Articles/Oak_Ridge_Researchers_Use_Air-Leak_Detection/a69313 A69313 Tue, 12 Sep 2023 07:00:00 GMT

Superlenses made of plasmonic materials and metamaterials can image features at the subdiffraction scale. However, intrinsic losses restrict the image resolution of superlenses, hindering their widespread use.

To compensate for optical loss in superimaging systems, researchers at the University of Hong Kong (HKU) devised a way to provide virtual gain. To do so, they synthesized excitation waves of complex frequency, based on measurements at real frequencies. By illuminating materials with synthetic frequency waves, the researchers were able to implement virtual gain experimentally and retrieve subwavelength features. The multifrequency approach from HKU could provide a practical solution to overcoming the intrinsic losses of...]]> https://www.photonics.com/Articles/Complex_Frequency_Waves_Compensate_for_Optical/a69311 A69311 Mon, 11 Sep 2023 07:00:00 GMT https://www.photonics.com/Articles/DRDC_Awards_Immervision_57M_to_Develop/a69310 A69310 Sat, 09 Sep 2023 07:00:00 GMT
The ability to image complex biological tissues is essential for many biological studies and clinical diagnostic applications. However, capturing detailed 3D images of thick biological samples is difficult, due to multiple light-scattering in the samples.

Optical diffraction tomography is still largely restricted to imaging thin objects such as cells and thin tissue slices. To allow for in vivo imaging with extended imaging depth, a full-field, reflection-mode measurement geometry needs to be implemented. Also, a comprehensive inverse-scattering model that accounts for the temporal dispersion and spatial aberration of the back-scattered field from thick, inhomogeneous media needs to be developed. In addition, the multiple-scattering...]]> https://www.photonics.com/Articles/Tomography_Technique_Images_Thick_Bio_Samples_at/a69307 A69307 Fri, 08 Sep 2023 07:00:00 GMT

Engineers at imec have integrated a pinned photodiode (PPD) structure in thin-film image sensors. According to the researchers, the addition of a pinned-photogate and a transfer gate into the thin-film image sensor architecture exploits the superior absorption qualities of thin-film imagers — beyond 1 µm.

Further, they said, the integration shows show that thin-film-based image sensors with a pinned photodiode structure can exhibit noise performance that is comparable to a silicon pinned photodiode pixel.

As a result, the advancement unlocks the potential of sensing light beyond the visible in a cost-efficient way.

Though the use of III-V materials can overcome this long-held detection range limitation, the...]]> https://www.photonics.com/Articles/Imec_Applies_Pinned_Photodiode_Structure_to/a69278 A69278 Mon, 28 Aug 2023 07:00:00 GMT
Raman spectroscopy is a useful tool for identifying microplastics — plastic particles smaller than 5 mm — although conventional point confocal Raman methods are limited to single-point detection, limiting the detection speed. A line-scan Raman spectroscopy method developed by the Chinese Academy of Sciences and Cardiff University significantly boosts detection speed for both micro- and nanoplastics.

The researchers reported a line-scan Raman microspectroscopy system capable of rapid imaging and chemical identification of microplastics down to 2000 nm in size, and capable of imaging a 40- × 10-µm particle in 10 s, representing a speed improvement by about two orders of magnitude compared to confocal imaging.
