Question: Why Antimicrobial agents have been encapsulated in liposomes?
Antimicrobial agents have been encapsulated in liposomes for two reasons.
First, they protect the entrapped drug against enzymatic degradation. For instance, the penicillins and cephalosporin are sensitive to the degradative action of β-lactamase, which is produced by certain microorganisms.
Secondly, the lipid nature of the vesicles promotes enhanced cellular  uptake of the antibiotics into the microorganisms, thus reducing the  effective dose and the incidence of toxicity as exemplified by the  liposomal formulation of amphotericin B.
2: Name Any three components of Microfluidics?
Microvalves
Microfilters
Microsensors

Why Carbon Nano tubes are used as a catalyst in PCR?

Dispersion of CNTs in different phases enhances the thermal conductivity of suspensions as compared to the dispersed phase of the working fluid. Therefore, CNTs have the potential role as a PCR catalyst.
