Shadow length greater than 18; from about 88 wt.% to about 99.9 wt.% water carrier; and from about 0.1 wt.% to about 5 wt.% emulsifier selected from the group consisting of anionic, non-ionic, cationic and amphoteric.

The present invention discloses a multifunctional recovery physiotherapy instrument of novel polarization oscillation wave depth thermotherapy. The multifunctional recovery physiotherapy instrument comprises a high frequency oscillation generator connected with a hand-held electrode and a pedal electrode, and an oscillation wave is introduced from the feet, the hands or other parts of a human body via the electrodes, so that a polarization oscillation energy wave similar to the pulse discharge between the capacitor plates is formed between the two electrodes, and accordingly, the human body cell molecular charges generate a polarization displacement heat effect to form the depth thermotherapy. The heat is generated by the cell resonance, so that the body depth heating is more uniform, the human body does not feel discomfort when the temperature in the body rises to 42 DEG C, and the body lesion location can be heated directionally and effectively, and accordingly, the unique effects of killing viruses, eliminating inflammation, restraining tumors and cancer cells, etc., are realized. The multifunctional recovery physiotherapy instrument can be widely suitable for the treatment of various inflammations and tumors, is small in size and remarkable in curative effect, is simple and convenient to use and operate, is safe and reliable, is suitable for being used at the places, such as the hospitals, the health centers, nursing homes, etc., and has a great practical value.

The invention discloses a fluorescent probe for detecting water content in an organic solvent and its preparation method and application. There are two fluorescent probes named TPEB-m-NO respectively. 2 , TPEB‑p‑NO 2 , the corresponding chemical structural formula is shown in formula I and formula II; it is made of raw material 4,7-dibromobenzo[c][1,2,5]thiadiazole, (3-nitrophenyl)boronic acid or ( 4‑nitrophenyl)boronic acid, 4,4,5,5‑tetramethyl‑2‑(4‑(1,2,2‑triphenylvinyl)phenyl)‑1,3,2‑di The oxaborolane is synthesized and purified in two steps under the action of a catalyst; the invention also discloses spectral properties such as fluorescence changes of the fluorescent probe in the process of detecting solvent water. Research proves that the fluorescent probe of the present invention can quantitatively detect trace amounts of water in tetrahydrofuran and dioxane through the joint action of twisted intramolecular charge transfer and aggregation-induced luminescent mechanism.

The invention provides an organic silicon small molecule fluorescent probe for detecting hypochlorous acid, and the chemical structural formula is: The probe itself is in a fluorescent state and emits fluorescence of naphthalimide. After the addition of hypochlorous acid, the naphthalimide in the probe interacts with hypochlorous acid to affect the intramolecular charge transfer (ICT) process, resulting in partial fluorescence quenching of the probe naphthalimide. When glutathione was added, the quenched fluorescence was recovered. The probe has novel recognition site, fluorescence recovery, fast response speed and strong anti-interference ability. It is synthesized by heating 1,3-bis(3-aminopropyl)-1,1,3,3-tetramethyldisiloxane and 5-methylthio-1,8-naphthalenedicarboxylic anhydride in ethanol to synthesize The raw materials are readily available and the process is simple. The probe has potential application value in the field of laser-excited fluorescent biomarkers and the study of the physiological function of hypochlorous acid in biological samples.

The invention provides a high-stability wash-free SNAP-tag probe and its preparation method and application. The probe is based on a 4,5-position disubstituted naphthalimide dye, and benzylguanine is used as a targeting group. group, its structural formula is shown in (1). The azetidine structure at the 4,5-position of the probe largely inhibits the generation of TICT (twisted intramolecular charge transfer), allowing the naphthalimide molecule to maintain high stability while being resistant to polarity changes. not sensitive. The probe is able to complete in 2 minutes (t 1 / 2 =8s) specifically binds to SNAP-tag, and achieves an 8-fold fluorescence enhancement after binding, realizing wash-free fluorescence imaging of SNAP-tag in living cells.
