Multimodal microrobots are of growing interest due to their capabilities to navigate diverse terrains, with promising applications in inspection, exploration, and biomedicine. Despite remarkable progress, it remains challenging to combine the attributes of excellent maneuverability, low power consumption, and high robustness in a single multimodal microrobot. We propose an architected design of a passively morphing wheel that can be stabilized at distinct geometric configurations, relying on asymmetric bending stiffness of bioinspired tentacle structures.

Article Synopsis
  • - This study aimed to improve understanding of how tumors use lipids for energy and spread by observing lipid and collagen changes in real-time within living tumors, as traditional methods were ineffective for this purpose.
  • - Researchers created a new imaging technique that combines two methods—CARS and SHG microscopy—to monitor intratumoral lipid droplets and collagen in a mouse model of breast cancer.
  • - The findings revealed that monitoring lipid droplet characteristics can help evaluate the effectiveness of cancer treatments and better understand lipid metabolism and its impact on tumor growth.

Long-term, repeatable monitoring of the appearance and progress of Alzheimer's disease (AD) in real time can be extremely beneficial to acquire highly reliable diagnostic insights, which is crucial for devising apt strategies towards effective AD treatment. Herein, we present an optimized innovative cranial window imaging method for the long-term repeatable imaging of amyloid-β (Aβ) plaques and vessels in an AD mouse model. Basically, two-photon excitation fluorescence (TPEF) microscopy was used to monitor the fluorescently labeled Aβ plaques, whereas the label-free blood vessels were studied using coherent anti-Stokes Raman scattering (CARS) microscopy in the live in vivo AD mouse model.

Article Synopsis
  • Elastic stretchability and function density are crucial for advancing stretchable inorganic electronics, but previous designs often limited function densities to below 80%.
  • The introduction of stacked multilayer network materials allows for better integration of components and stretchable interconnects, significantly improving elastic stretchability (by about 7.5 times) compared to traditional soft elastomers.
  • This new approach has enabled the creation of a compact electronic system (11 mm by 10 mm) with moderate elastic stretchability (around 20%) and exceptional areal coverage (over 110%), which can be used for various applications like a compass display and physiological monitoring.

Objective: To study the volatile compounds of Salix babylonica, and to provide scientific basis for efficacy of attracting natural enemies and medicinal value of Salix babylonica.

Methods: The volatile compounds were collected from Salix babylonica by dy- namic headspace absorption method, and analyzed by gas chromatography-mass spectrum( GC-MS).

Results: Forty-one volatile com- pounds were identified from Salix babylonica.
