Abstract: A discovery of the conversion of amorphous calcium polyphosphate (ACPP) or/and other polyphosphate salts with various type of calcium phosphate to new calcium phosphate product (i.e. dicalcium phosphate dihydrate (DCPD)) in a liquid environment. The discovery includes mixing a various type of calcium phosphate with an aqueous ACPP or/and other polyphosphate salts gel, which is fast setting and possessing strong mechanical strength, and can be gradually converted to DCPD/hydroxyapatites in physiological condition. This injectable past can be applied as alternative of conventional CPC bone cement that is suitable for bone void repair due to its excellent properties in osteoconductivity and osseointegration. It can also be applied as drug delivery device in tissue engineering for its strong bonding to drug molecules.

Abstract: This disclosure provides an impedance cytometer which includes a carrier that can be attached to a living being, with a biosensor mounted thereto. The bio sensor includes a microfluidic flow channel, formed in the carrier, and an impedance circuit. The microfluidic flow channel accommodates passage of a particle therethrough. The impedance circuit, connected to the microfluidic flow channel, includes a signal generator that produces a high-frequency drive signal applied to the flow channel to produce a biosensor output signal having high-frequency variation resulting from the drive signal and low-frequency variation resulting from impedance variation within the flow channel during the particle's passage. A lock-in amplifier is disposed to (i) amplify the bio sensor output signal, (ii) mix the amplified signal with the drive signal, and (iii) frequency-filter the mixed, amplified signal to output an impedance signal representing the low-frequency impedance variation resulting from the passage of the particle.
