We have developed a theranostic nanoparticle delivering the model radionuclide 177 Lu based on the versatile lipid-calcium-phosphate (LCP) nanoparticle delivery platform. Characterization of 177 Lu-LCP has shown that radionuclide loading can be increased by several orders of magnitude without affecting the encapsulation efficiency or the morphology of 177 Lu-LCP, allowing consistency during ...

PLGA Nanoparticles were also used to co-deliver D-atocopheryl polyethylene glycol succinate (Vitamin E TPGS) along with docetaxel to enhance cytotoxicity against multi-drug resistant. Vitamin E TPGS acts as an inhibitor to MDR associated proteins and can be used to enhance the therapeutic efficacy of chemotherapeutic drugs such as docetaxel.

Angewandte Chemie International Edition: Vol 59, No 50

Metal nanoparticle surfaces rapidly catalyze non-redox ester hydrolysis in the presence of redox H 3 N−BH 3. Metal hydrides on a Pt nanoparticle might assist nucleophilic attack of H 2 O on the carbonyl group of an ester. The ester hydrolysis is applied in a sensitive electrochemical immunosensor for thyroid-stimulating hormone detection.

A 2020 recent study published by Danish researchers, for example, demonstrated that LDL-C the lowest risk of all-cause mortality was found at an LDL-C concentration of 3.6 mmol/L (140 mg/dL). In comparison the highest association with all-cause mortality was actually at LDL-C levels of less than 1.8mmol (70mg/dL).

Due to the fact that most currently available PSs absorb light at low wavelength, ZnO NP is a good candidate in improving PDT efficiency because its UV emission upon X-ray excitation more or less matches the UV absorption of most PSs, and hence has a good potential to serve as an irradiation source for PDT on deep-seated tumors.
