Elucidating subcellular architecture and dynamics at isotropic 100-nm resolution with 4Pi-SIM.

Three-dimensional structured illumination microscopy (3D-SIM) provides excellent optical sectioning and doubles the resolution in all dimensions compared with wide-field microscopy. However, its much lower axial resolution results in blurred fine details in that direction and overall image distortion. Here we present 4Pi-SIM, a substantial revamp of IS that synergizes 3D-SIM with interferometric microscopy to achieve isotropic optical resolution through interference in both the illumination and detection wavefronts.

Monitoring of viral myocarditis injury using an energy-confined upconversion nanoparticle and nature-inspired biochip combined CRISPR/Cas12a-powered biosensor.

The early diagnosis and timely intervention of viral myocarditis urgently require a noninvasive detection approach. Therefore, we present a CRISPR/Cas12a-powered biosensor that integrates an exceptionally efficient upconversion luminescent resonance energy transfer (LRET) with a nature-inspired biochip to determine a golden-standard cardiac biomarker (cardiac troponin I). First, a unique sandwich-structured energy-confined upconversion nanoparticle (acting as the energy donor) is synthesized to dramatically reinforce the LRET's ability.

Light-Activated and Self-Driven Autonomous DNA Nanomachine Enabling Fluorescence Imaging of MicroRNA in Living Cells with Exceptional Precision and Efficiency.

Owing to their favorable design flexibility and eminent signal amplification ability, DNA nanomachine-supported biosensors have provided an attractive avenue for intracellular fluorescence imaging, especially for DNA walkers. However, this promising option not only suffers from poor controllability but also needs to be supplied with additional driving forces on account of the frequent employment of metal ion-dependent DNAzymes. Aiming at overcoming these obstacles, we introduce some fruitful solutions.
