Nile red (Nile blue oxazone) is a lipophilic stain. Nile red has environment-sensitive fluorescence. Nile red is intensely fluorescent in a lipid-rich environment while it has minimal fluorescence in aqueous media. Nile red is an excellent vital stain for the detection of intracellular lipid droplets by fluorescence microscopy and flow cytof uorometry. Nile red stains intracellular lipid droplets red. The fluorescence wavelength is 543/598 nm .

Methyl α-D-mannopyranoside (α-Methyl-D-mannoside) is a methyl glycoside derivative and conformational stabilizer of α-D-mannopyranose. The glycosidic bond conformation of Methyl α-D-mannopyranoside is significantly affected by the environment. In aqueous solution, Methyl α-D-mannopyranoside stabilizes into a trans conformation via intermolecular hydrogen bonds; in the gas phase, however, steric interactions drive Methyl α-D-mannopyranoside to prefer a clockwise gauche conformation. Methyl α-D-mannopyranoside also serves as a major component of secondary cell wall polymers in some bacteria and an active precursor site for virus-targeted glycoproteins. Methyl α-D-mannopyranoside acts as an acceptor substrate for alternansucrase, mediating the transfer of D-glucopyranosyl groups to generate a variety of glycosylated oligosaccharide products, with methyl α-D-glucopyranosyl-(1→6)-α-D-mannopyranoside as the main component. Methyl α-D-mannopyranoside is applicable to studies on bacterial pathogenic mechanisms associated with mannose-specific fimbrial lectins .

BADAN is a thiol-reactive, environment-sensitive fluorescent probe used for site-specific labeling of protein cysteine residues to detect protein topology, local polarity, protein-lipid interactions, and conformational changes. The bromoacetyl group of BADAN covalently binds to cysteine thiols, and its fluorescence originates from the intramolecular charge transfer (ICT) excited state. The emission peak position varies with the polarity of the surrounding medium: it blue-shifts to approximately 488 nm in nonpolar environments (such as the hydrophobic core of lipid bilayers) and red-shifts to approximately 496-507 nm in polar environments (such as aqueous phases), independent of enzymes, pH, or membrane potential. Ex = 380-402 nm; Em = 400-600 nm .

Research Areas:
DOCP (2-((2,3-Bis(oleoyloxy)propyl)dimethylammonio)ethyl hydrogen phosphate), characterized by their inverted charge orientation compared to traditional phosphocholine (PC) lipids, feature a quaternary amine positioned near the bilayer interface and a phosphate group that protrudes into the aqueous environment. This unique configuration of iPC lipids provides an exceptional opportunity to explore the biophysical properties and bioactivity implications resulting from the charge inversion at the bilayer surface.

Propargyl-PEG4-Ms has an alkyne group and a mesylate group. The mesylate group is a sulfonate ester for nucleophilic substitution reactions (SN2). The alkyne group can react with azides via copper catalyzed Click Chemistry reactions. The PEG units help increase the solubility of the molecule in aqueous environments.

TPAPyN is a nitroreductase(NTR)-responsive type I photosensitizer. TPAPyN facilitates the imaging of hypoxic cancer cells and image-guided photodynamic therapy (PDT). TPAPyN does not emit fluorescence in the aqueous environment, but restores when NTR cleaves the nitrofuran quencher with aggregation-induced emission. TPAPyN can be used as a fluorescent probe for specific imaging of hypoxic cancer .

NRERcl is the fluorescent scaffold of Nile Red (HY-D0718). NRERcl can be used for imaging of endoplasmic reticulum lipid order and polarity. NRERcl carries a propyl chloride targeting group that directs it to the endoplasmic reticulum, and it acts through excited-state charge transfer, enabling emission color changes according to local polarity associated with lipid order. NRERcl can insert into lipid bilayers, showing almost no fluorescence in aqueous environments and a substantial increase in fluorescence upon entering membranes. NRERcl can also stain Golgi membranes. NRERcl has an excitation wavelength of 520 nm, and its emission maximum varies with the environment (Ex/Em = 520/584-653 nm) .

Photoswitchable PM8 is a fluorescent probe used for super-resolution imaging of the plasma membrane. Photoswitchable PM8 functions through a light-induced Z/E isomerization mechanism: in the hydrophobic cell membrane environment, the Z isomer forms a planar intramolecular charge transfer state stabilized by an intramolecular hydrogen bond, which restricts conformational freedom, reduces nonradiative decay, and produces bright fluorescence; in contrast, the E isomer lacks this hydrogen bond, has increased conformational freedom, and exhibits a fluorescence-quenched state. The fluorescence of Photoswitchable PM8 can be switched "on/off" by visible light: activation with 405 nm light forms the fluorescent Z isomer, and switching with 561 nm light converts it to the nonfluorescent E isomer. In the membrane environment, Photoswitchable PM8 enables single-molecule localization for super-resolution imaging. Due to solvent-induced quenching and aggregation, Photoswitchable PM8 has negligible fluorescence in aqueous solution, but upon binding to the hydrophobic membrane environment it produces bright fluorescence, enabling high signal-to-noise ratio imaging without washing .

TPE-2E N-oxide is a fluorescent probe used for hypoxia detection and tumor hypoxia imaging. Due to its active intramolecular motion, TPE-2E N-oxide shows no fluorescence in aqueous solution. In hypoxic environments, its N-oxide group undergoes two-electron reduction by CYP450 reductase and other heme protein reductases expressed under hypoxia, forming hydrophobic aggregates that trigger aggregation-induced emission through the restriction of intramolecular motion. TPE-2E N-oxide exhibits selective lipid droplet localization in cells. The absorption wavelength of TPE-2E N-oxide in dichloromethane is 313 nm; in a 99% hexane/dichloromethane mixed system, its excitation wavelength is 330 nm and emission wavelength is 460 nm. For in vitro cell imaging, excitation is performed at 405 nm, with an emission wavelength range of 430-560 nm .
