We describe a visible dye-based staining method for DNA in polyacrylamide gels using ethyl violet (EV). The novel method is a background-free, sensitive, economical, and simple procedure involving only staining and washing steps that can be completed within 30 min. As little as 0.8-1.6 ng of phiX174 DNA/HaeIII can be detected by EV, which is about eightfold more sensitive than Nile blue (NB) stain and twofold less sensitive than ethidium bromide (EB) stain.

Long-standing ulcerative colitis (UC) is associated with an increased risk of developing colorectal neoplasia. Both dye-based chromoendoscopy (DCE) and virtual chromoendoscopy (VCE) increase detection of neoplastic lesions. In this prospective randomized controlled trial (RCT), we compared the neoplasia detection rate between DCE and i-scan VCE in patients with long-standing UC.

Article Synopsis
  • A new sensor called PDN has been developed that can selectively detect copper (Cu) and L-cysteine using a fluorescence On-Off-On approach and exhibits unique aggregation-induced emission enhancement (AIEE) properties.
  • The sensor's effectiveness relates to its diazo functional group and specific molecular design, which contributes to its behavior, including a bathochromic shift due to J-aggregate formation.
  • PDN shows impressive sensitivity with detection limits of 0.113 nM for Cu and 84 nM for L-cysteine and has been tested successfully in real-world samples, including strong acids and bases, and confirmed through various analytical methods and computational calculations.

The significance of thermochromic materials in a wide range of applications makes their research and development highly desirable. Herein, three new thermochromic isomorphous supramolecular materials based on the 5,5'-indigodisulfonate ion of the indigo carmine dye, with formulas [Cu(HO)](CHNOS)·2HO (), [Ni(HO)](CHNOS)·2HO (), and [Co(HO)](CHNOS)·2HO (), are reported. These materials exhibit thermochromic properties, with a color change from red-bronze to grayish-red after the first step of their dehydration process completed around 80 °C (conversion of to [Cu(HO)(CHNOS) ()]), and then, this grayish-red color becomes lighter after the second step, which is completed around 230 °C (conversion of to [Cu(CHNOS)] ()).

Developing color-tunable ultralong room temperature phosphorescence (RTP) materials with variable afterglow is essential for applications in displays, sensors, information encryption, and optoelectronic devices. However, designing full-color ultralong RTP for persistent luminescence remains a significant challenge. Here, we propose a straightforward strategy to achieve predictable full-color afterglow using readily available disperse dyes in polymeric systems, the phosphorescence resonance energy transfer (PRET) process.

Dye-based fluorescent organic nanoparticles are a specific class of nanoparticles obtained by nanoprecipitation in water of pure dyes only. While the photophysical and colloidal properties of the nanoparticles strongly depend on the nature of the aggregated dyes, their excellent brightness in the visible and in the near infrared make these nanoparticles a unique and versatile platform for in vivo application. This article examines the promising utilization of these nanoparticles for in vivo optogenetics applications.
