Doubly capped nanocrystals: A new technique was developed for coating of colloidal inorganic nanoparticles with different surface properties with a thin, cross‐linked, and functionalized shell containing organic and inorganic layers (see picture). The underlying amphiphilic polymer foundation arranges on the particle surface as predicted in past reports.

Early laparoscopic cholecystectomy is safe and feasible for acute cholecystitis with the additional benefit of shorter total hospital stay. Apart from a shorter operating time, treating patients with delayed laparoscopic cholecystectomy does not offer additional benefit.
