Acoustic cell patterning reveals geometry- and substrate-dependent vasculogenesis and human embryo model development
Abstract Precise spatial organization of cells is critical for engineering functional tissues and constructing human developmental models. Here, we report the development of acoustic cell patterning (ACP), an ultrasound-based method capable of rapidly generating spatial patterns of multiple cell types on both rigid and compliant substrates without requiring chemical or physical modification of the substrates.
Coaxial line-scanning Brillouin microscopy
Abstract Confocal Brillouin microscopy (CBM) enables high-resolution mechanical imaging but has slow acquisition speeds due to its point-by-point scanning strategy. Line-scanning Brillouin microscopy (LSBM) offers imaging acquisition speed improvements but faces challenges such as beam distortion in biaxial configurations and insufficient extinction ratio due to the single-stage VIPA spectrometer.
Versatile multimodal modality based on Brillouin light scattering and the photoacoustic effect
Abstract Multimodal optical techniques are useful for the comprehensive characterization of material properties. In this work, we developed a new, to the best of our knowledge, multimodal technology that can simultaneously measure a subset of mechanical, optical, and acoustical properties of the sample and is based on the integration of Brillouin (Br) and photoacoustic (PA) microscopy. The proposed technique can acquire co-registered Br and PA signals from the sample.

Qualitative and Quntitative Recognition of Chiral Drugs Based on Terahertz Spectroscopy
Qualitative and Quntitative Recognition of Chiral Drugs Based on Terahertz Spectroscopy Zefang Wang, Yan Peng, Chenjun Shi, Liping Wang, Xiaohong Chen, Wanwan Wu, Xu Wu, Yiming Zhu, Jingchen Zhang, Guiliang Cheng and Songlin Zhuang Abstract Chiral drugs are drugs with chiral or asymmetric centres in their molecular structure. Different enantiomers of the same chiral drug have noticeably different pharmacological activities and pharmacokinetic properties.
Molecular methylation detection based on terahertz metamaterial technology
Molecular methylation detection based on terahertz metamaterial technology Terahertz wave has a good ability to identify biomolecules due to its fingerprint spectrum characteristics. However, the minimum detectable limit of terahertz technology by conventional tablet pressing method is in the order of milligram, which cannot meet the application requirements of low concentration detection in biomedical field—near or below microgram.
