“…As all of these problems had been reported in many nanoparticles (e.g., liposomes, micelles, nanospheres, and nanofibers) [1], finding an ideal drug delivery with an optimal size, shape, and surface characteristic including the specific target binding size is still a challenge for scientists. The minicell is described as a type of abnormal division in bacteria, which came from a mutation or stress environment [3], resulting in a small spherical bacterium with a diameter less than 1 μm. Scientists suggested that this was a new term for "nanocells" due to the fact that it has its diameter at the scale of nanometers.…”
