With the completion of the human genome-sequencing project, there has been a resulting change in the focus of studies from genomics to proteomics. By utilizing the inherent advantages of molecular beacon probes and biofunctionalized nanoparticles, a series of novel principles, methods and techniques have been exploited for bioanalytical and biomedical studies. This review mainly discusses the applications of molecular beacon probes and biofunctionalized nanoparticles-based technologies for real-time, , highly sensitive and highly selective protein analysis, including the nonspecific or specific protein detection and separation, protein/DNA interaction studies, cell surface protein recognition, and antigen-antibody binding process-based bacteria assays. The introduction of molecular beacon probes and biofunctionalized nanoparticles into the protein analysis area would necessarily advance the proteomics research.

In this work, a new dual-signal fluorescence strategy based on nano-gold molecular beacon (MB) and in-situ generated silver nano-clusters (NCs) coupled with multiple amplification technique was developed for sensitive detection of miRNA (let-7b). miRNA can recognize both hairpin probe (HP) and auxiliary DNA, inducing dual-cycle amplification-process to release plenty of DNA S2. As the report probe carboxyfluorescein (FAM) was modified on Au nanoparticles (AuNPs), the fluorescent signal was quenched due to the fluorescence resonance energy transfer (FRET).

Interleukin-15 (IL-15) emerges as a promising immunotherapeutic candidate, but the therapeutic utility remains concern due to the unexpected systematic stress. Here, we propose that the mRNA lipid nanoparticle (mRNA-LNP) system can balance the issue through targeted delivery to increase IL-15 concentration in the tumor area and reduce leakage into the circulation. In the established Structure-driven TARgeting (STAR) platform, the LNP and LNP can effectively and selectively deliver optimized IL-15 superagonists mRNAs to local and lungs, respectively, in relevant tumor models.

The rotavirus-led fatal infantile gastroenteritis in the globe demands a portable, specific, and low-cost diagnostic tool for its timely detection and effective surveillance in a mass population. Consequently, the design and development of an advanced biosensing technique for its detection is of paramount importance. A highly conserved 23-nucleotide sequence, 5' GCTAGGGATAAGATTGTTGAAGG 3', was identified by a human rotavirus A VP6 gene sequence analysis and designated as the target.

When a body is discovered at a crime or murder scene, it is crucial to examine the body and estimate its postmortem interval (PMI). Accurate estimation of PMI is vital for identifying suspects and providing clues to resolve the case. MicroRNAs (miRNAs or miRs) are small non-coding RNAs that remain relatively stable in the cell nucleus even after death-related changes occur.
