Abstract: A method for estimating total body water, TBW, content of a subject, comprises: receiving locally measured bioimpedances for at least two different frequencies of a stimulation current at a body part of the subject; determining a first resistance and a second resistance of the bioimpedance, wherein the first resistance corresponds to a representation of the bioimpedance being purely resistive at a low frequency of the stimulation current and the second resistance corresponds to a representation of the bioimpedance being purely resistive at a high frequency of the stimulation current; and estimating the TBW content of the subject using a ratio between the first resistance and the second resistance.

Abstract: A method for producing a blood filter, the blood filter being a filter for filtering blood, the method comprising



providing a first layer;
providing a block copolymer layer above the first layer;
converting the block copolymer layer to a mask by selectively removing domains of the block copolymer layer;
etching pores through the first layer in regions exposed by the mask;
wherein a pore size is below 20 nm, the pore size preferably being 6.6 nm or smaller.
