Fluorescence imaging techniques, such as optical sectioning and light sheet microscopy, enable to reconstruct the 3D distribution of chemicals within a sample. However, current methods rely on exogenous labels, from which considerable perturbation may be introduced in living systems. Raman imaging offers a feasible solution to visualize components in biological samples in a label-free manner. Besides, the integration of Raman microscopy with 3D approaches will benefit the research of biomedical samples on novel devices, which is dominated by the strongly enhanced spatial resolution, imaging speed, and overall field of view as well as complemented more details of samples. In this overview, recent achievements in 3D visualization of biological samples from the Raman perspective, are explored including scanning mechanism, light sheet, tomography strategy, compressive sensing, holography, and tissue clearing. Importantly, these platforms are compatible with biomedical research, thus allowing the imaging of chemical constituents and the distribution of samples in a whole volume. As a unique volumetric imaging tool for biological discovery, these methods may provide a strategy to accelerate new discoveries across diverse fields of research.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"21 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It enables us to amplify or suppress the outgoing waves via engineering amplitudes and phases of multiple incidences. However, within a purely spatially (temporally) engineered medium, coherent wave control requires the frequency of the associated incidences to be identical (opposite). In this work, this conventional constraint is broken by generalizing coherent wave control into a spatiotemporally engineered medium is broken, i.e., the system featuring a dynamic interface. Owing to the broken translational symmetry in space and time, both the subluminal and superluminal interfaces allow interference between scattered waves regardless of their different frequencies and wavevectors. Hence, one can flexibly eliminate the backward- or forward-propagating waves scattered from the dynamic interfaces by controlling the incident amplitudes and phases. The work not only presents a generalized way for reshaping arbitrary waveforms but also provides a promising paradigm to generate ultrafast pulses using low-frequency signals. It has also implemented suppression of forward-propagating waves in microstrip transmission lines with fast photodiode switches.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"18 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detecting low-abundance mutant genes in blood is challenging but crucial for personalized treatment plans. Herein, a novel platform combining catalytic hairpin self-assembly (CHA)-mediated self-calibrating surface-enhanced Raman spectroscopy (SERS) with a high-throughput Raman system (CCSPS) was designed. This platform enables ultrasensitive and rapid genotype analysis of gene mutations. The development of CCSPS specifically targets <i>EGFR</i> mutations, which serve as crucial therapeutic targets for precision therapy in lung cancer. This system shows excellent sensitivity and selectivity, capable of detecting multiple <i>EGFR</i> mutations (<i>Del-19</i>, <i>L858R</i>, and <i>T790M</i>) with a detection limit as low as attomolar levels. Additionally, precise genotyping analysis was successfully conducted on 42 clinical samples using the CCSPS, yielding results consistent with those obtained through next-generation sequencing. These results underscore the efficacy of the CCSPS in noninvasively identifying circulating tumor DNA (ctDNA) mutations, facilitating immediate therapeutic decision making at the bedside.

To overcome this limitation, angle-based neuromorphic wave normal sensing, which serves as a differentiable framework developed on the asynchronous event modality is proposed. Herein, it is illustrated that the emerging computational neuromorphic imaging paradigm enables a direct perception of a high-dimensional wave normal from the highly efficient temporal diversity measurement.

Furthermore, A-site regulation demonstrates that increasing Cs⁺ content induces enhanced Jahn–Teller distortion, thereby boosting luminescence efficiency. However, the pure Rb sample exhibits the lowest thermal activation energy, as the temperature rises, increased phonon-exciton coupling and the defect activity accelerate the nonradiative recombination, drastically decreasing fluorescence lifetime by two orders of magnitude from 300 to 390 K. Utilizing this exceptional thermal sensitivity, a lifetime-based fluorescence thermometer is developed, attaining a breakthrough relative sensitivity reaching 20.69% K<sup>−1</sup> at 390 K, with high repeatability across multiple heating and cooling cycles.

The development of materials capable of PersL over a wide temperature range, represents a significant hurdle in the advancement of PersL technology. Here, this study deviates from the conventional method of relying on inherent traps and instead harness recoverable Frenkel defects within fluoride materials to broaden the operational temperature range for PersL. Under X-ray irradiation, Frenkel defects involving the migration of fluorine ions can be generated and recovered in real time, accompanied by the formation and dissipation of localized excitons, ultimately transferring energy to the luminescent centers. Notably, this recovery process is operative at all temperatures and is sufficiently slow-paced, ensuring that PersL can be observed across every temperature range (77–500K). Building on this mechanism, the production of multicolor wide-temperature PersL is readily attainable through the straightforward substitution of various luminescent centers. Significantly, X-ray-induced recoverable Frenkel defects have the potential to confer the characteristics of wide-temperature PersL to materials that inherently lack these attributes. This, in turn, provides a new design strategy for developing wide-temperature PersL materials.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"75 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
